HI ALL!
I make mistake, I want install <<<edited>>>, for check this SO, but allways send error with USB port, I think, in the BIOS disable all USB, but I don´t remember that motherboard only used USB for keyboard. Now i can´t change this mistake. I proceded to remove batery for 12 hs, but nothing. I hope I can clear my bios. Thank for your time, and sorry for mmy english.

WALTHERIUS, we do not discuss anything to do with installation of Apple's products here that is specifically against their EULA for legal reasons. Since the OS you chose isn't important to the problem you are having with your motherboard, I am deleting that part of your post. Please do not reference doing this on these forums again.

Thank you.

be sure to unplug system from socket should be a jumper on the board or a cmos clear button check your mb manual

Thank for your answer, but I read first the manual, it say for clear CMOS, unplug the batery for 1 hs. and then put it, and BIOS wil be reset.
But it not work. I download update for my BIOS, to boot from CDROM, put jumper into 2-3 pin, but too , don´t work. The sevice oficial say it easy from CDROM update, because it will done, all setting will be reset. I don´t know what´s not work. I will be work in this problem tomorrow. Maybe send mail to INTEL directly. Well , thank for your time, again.

WALTHERIUS,

I have the exact same scenario.

I have a DP45SG. Tried installing <<<edited>>>. Thought to disable USB from BIOS. Can't change BIOS back.

The BIOS recovery says that you need to pull the BIOS configuration jumper off and start the computer with the BIOS recovery CD in your CD drive. It will then automatically update the BIOS and shutdown. When I try to do this I get a black screen and my CD drive spins but nothing happens. I can leave it like this for 10 or 20 minutes with no change to the screen or my computer.

I was wondering if you had tried this or if you had solved your problem some other way. <<<edited>>>

Let me know what you have done or will do to correct the USB problem. Thanks.

craley1, what I posted to WALTHERIUS also applies to you too. Please do not post about this type of activity that is specifically against Apple's EULA with their operating system. This is for legal reasons, since Apple is notoriously suit-happy when dealing with their IP.

Thanks,

See my email from a couple of weeks ago to Intel support below (I haven't received a reply yet).

My one last hope is to try the Toolkit software that comes on the mobo software CD.
If I can use a boot cd that gets me into Windows and also enables legacy USB for the keyboard, as I think my Knoppix boot cd did, I may be able to edit the BIOS from Windows by using the Toolkit. I can't try this until I get my video card back from the person I lent it to, to replace his faulty ATI 4850.

Is anyone else able to fix their BIOS? It seems dumb to allow disabling of USB and then be unable to use a keyboard. Without PS2 you are screwed.I think there is a serious bug if even clearing CMOS and reflashing BIOS doesn't fix it.

I may try the undocumented CMOS jumper pins (not the BIOS jumpers, look on the mobo for label) and this time power up, to see if that will clear CMOS settings, but am hesistant to try it without knowing what it will do, since it is not mentioned in the Intel docs I have seen for the DP45SG.

Email to Intel:
===========================
USB disabled on DP45SG mobo with EQ8200 cpu.

I received a DP45SG as a gift and just built a system with it last week. Due to a faulty ATI 4850 GPU which caused fatal blue screen on boot, I entered BIOS to switch off a few "unneeded" features.
Figuring I was not booting from a USB device, I disabled USB ports and rebooted, just before realizing [D'OH!] that the DP45SG only has keyboard input via USB, no PS2 port is included on this board, so now I have no way to change BIOS settings.

I reflashed the BIOS after clearing CMOS by removing the battery and waiting over an hour.
Still, the BIOS USB was not reset to default to "On" as there was still no response to keyboard input. I even bought a PCI card with USB ports hoping to get around it that way, but no luck.
Is there any way to fix this? I don't want to have to send the board in for warranty replacement if there is some other way to get USB ports enabled without a keyboard.

Note: I also tried the CMOS jumper pins [UNDOCUMENTED - NOT THE BIOS JUMPERS] (without applying power) to reset CMOS, but that did not work.
The CMOS was cleared since I got a CMOS error on booting but I reflashed BIOS again successfully via boot CD .BIO file.

Please advise on how to proceed.
I even tried Intel Live Chat support but they could not help.

The problem isn't due to the OS they chose to try to install, but rather it's due to the crappy bios Intel used with this board. So the thread is edited and let stand for these folks to see if they can resolve the problems.

I mistakenly disabled USB while trying to diagnose an issue with a faulty brand new ATI 4850.
Since the keyboard is USB only, I can't even get into the BIOS to reset it.
Intel's website says to clear CMOS you unplug the power and remove the battery for an hour. Reflash the BIOS and the factory defaults should be restored.
This doesn't work for me, no matter what I try, including setting the jumper to boot straight into BIOS config, since the keyboard is still inoperative.
Intel allows you to shoot yourself in the foot with the DP45SG.

craley1 · 02-09-09, 09:56 PM

Okay... so I finally made a boot disc that works. Flashed the firmware and now when I start I get an Intel startup screen (does not recognize my F2 key). Moves over to a black screen with a blinking cursor but then does nothing else. I have even tried downgrading the BIOS to SG0102.BIO (only other version I could find). Looks like I'm doubly screwed now.

Does anyone know what the CMOS jumper pins do? I have removed the jumper and my computer started normally. I have jumpered 2 and 3 and nothing works but then I can go back and jumper 1 and 2 and the computer starts up fine.

My IT friend is telling me that if I remove the battery and jumper the 2 and 3 it should reset the CMOS and drain any capacitors. I did this for about an hour with no luck. I'm going to try a few more things since nothing is work on my comp right now. Does anyone know what those CMOS pins do or wha the pin configuration is?

craley1 · 02-11-09, 07:22 PM

Alright guys... here's the latest.

Yesterday (02.10.09) I talked with Intel tech support who were all kinds of useless. After they read through their manual on what to tell the customer, we finally went through everything I already knew. So the end results was to get a replacement board for frizee (minus shipping out of my pocket). Oh... and did I mention that the DP45SG is on backorder until 02.20.09. Last Intel motherboard I ever buy.

I am giving it one last shot by fixing it myself. I have ordered a PCI card with PS/2 inputs. It is waiting at the office for me right now so I'll have some time to play with it tomorrow and tell you if it works. If this does not plug and play immediately and allow me to alter BIOS with a PS/2 keyboard then I'm back to waiting until the DP45SG is back in stock and I have a PS/2 input for the next time I'm a dumbass.

WTF, Intel?

enb141 · 02-16-09, 10:03 AM

Guys for you that want to reset CMOS Settings, first you have to downgrade the BIOS to the oldest possible BIOS then update again to the newer bios, try that and I hope this works for you too.

manmachine · 02-17-09, 04:18 PM

Today I tried to install an old Windows XP. Installation failed by an IRQ error, so I tried to disable integrated peripherials step-by-step. I hoped that a simple CMOS clearing will set the whole system into default state.

But CMOS jumper simply does nothing! I measured the voltages on three pins. Center pin is on ground (0V), free pin is on +3V like any other motherboards. But if I connect them by the jumper, nothing happens at next startup.

I plugged a PCI-USB card into the computer, so my keyboard and mouse work under Vista but every other peripherials that I disabled before in setup don't work.

BIOS can not initialize this USB card, so keyboard unusable under booting.

I wrote an e-mail to Intel today.

(sorry for my English)

It is simply impossible, because IFLASH waits for you to press a key before stars to update flash memory.

vulcanman09 · 02-17-09, 08:17 PM

guys! you have to take the jumper completely off.
keep the jumper off.
then power up the computer for 30 seconds ( then shut off )
then replace the jumper on the exact same 2 pins
then power up the computer again.
the bios will be reset to the factory default settings

manmachine · 02-18-09, 02:56 AM

Thank you vulcanman09, I will try this method tonight.

manmachine · 02-18-09, 06:51 AM

Bad news: it doesn't work.

There is a "CMOS" jumper on motherboard, but it is not mentioned in manual or Intel's homepage. There are some words about removing battery, waiting an hour etc.

These actions do nothing.

It writes "cmos checksum error", "time not set" - but all peripherial stay disabled.
Flash updating from pendrive (flash recovery mode enables only one USB port if it detects a pendrive in it) runs perfectly, but also does nothing with bios settings.

vulcanman09 · 02-18-09, 11:26 AM

try turning the power switch off .
wait till the green power goes out.
then pull the jumper off.
wait 1 minute.
replace the jumper on pins 2 and 3.
turn power supply switch back on.
power up computer again
go into the bios and find what options were reset.
remember , neither of the 3 pins are to be jumpered in order to reset the cmos

Not that mode, you have to remove the BIOS Jumper (recovery mode) with a CD burned with SG0083.BIO file (remember to use a different bios from yours) the booteable CD will not work because you don't have USB enabled so you have to do as recovery mode and then it will remove your previous CMOS Settings.

If this doesn't works for you you have to edit the ISO Bios file SGP4510H.86A.0102.ISO in order to not check the keypresses
I did that with WinISO, just edit the autorun.bat and isolinux.cfg

remember to use a different bios from the one you have if you do with the same bios you have it will not work, trust me I've been in your same situation with no USB support and it took me days to find a way to fix it. The removing BIOS Jumper removing Battery simply doesn't works.

I'll check the CMOS Jumper according to vulcanman09 just for curiosity.

manmachine · 02-18-09, 01:39 PM

Thank you very much! I will try it!

vulcanman09 · 02-18-09, 04:05 PM

sorry !
i should have also stated , that you should also remove the cmos battry
after the green light on mobo stops glowing.

process correction.

turn off computer.
turn off power supply switch
wait till green light stops glowing.
remove cmos back-up battery.
remove normal operation jumper ( do not replace yet ) pins 1 and 2 jumpered
wait 10 minutes. ( found this online regarding factory intel boards )

replace cmos back-up battery
replace jumper on pins 2 and 3 ( enter the bios settings )
turn on power supply switch.
( on some factory intel boards, after a bios reset, the green light will blink )
fire up the computer.
the bios should be reset to factory default settings

manmachine · 02-18-09, 04:13 PM

Dear enb141,

I made the boot cd following your method, it has worked perfectly. I updated the bios from 0093 to 0102, the update was successfull. But there is no change in (non) operating of USB. (I have two USB keyboards, so I could try both of them)

Intel has answered my e-mail. They wrote, I had to remove battery for 24 hours. I do not hope that it will work. I think, something on my motherboard is dead.

enb141 · 02-18-09, 05:08 PM

My question do you had USB keyboard support before or you never had USB keyboard support?

The problem with this motherboard is that some keyboards doesn't works, I have three USB keyboards (Logitech Illuminated Keyboard, Mac Keyboard (the new one)) and Logitech Elite Keyboard, and from the three only one works the Old Elite Keyboard so try to use an old USB keyboard specially those that have PS2 to USB Adapter.

Yes, my keyboard worked on the day before yesterday. I disabled the integrated peripherials because I wanted to find a source of an IRQ error during installing windows XP. I have a PCI-USB card, and if I plug it, the previously installed Vista works with this keyboard and mouse. But not only USB is disabled. All devices what I disabled (audio, firewire, lan) do not work under Vista. So I think, the problem is not in the USB controller.

But... the bios recovery function works from USB pendrive, so I think, the south bridge is ok.

enb141 · 02-18-09, 05:40 PM

Which of the two methods that I've metion to you was used, the ISO edit or the Recovery BIO?

manmachine · 02-18-09, 05:46 PM

I used ISO edit, and it ran without problems.

enb141 · 02-18-09, 06:03 PM

Weird, ok, do this same thing using ISO Edit, upgrade now to 0108 if still you don't have USB Support go and downgrade to 0083 this one doesn't have ISO on their website but you can use it editing the ISO File with SG0083.BIO on it.

I was in the same situation as you were, my USB were not working on OSX so I started to disable LAN, Audio, then Legacy USB and finally USB which give me problems but my solution worked to me, I hope this works for you.

manmachine · 02-18-09, 06:49 PM

Dear enb141,

Thank you! Thank you! Thank you! Thank you! Thank you! Thank you! Thank you!

I made an ISO image using the "frame" of 0102 but I replaced the BIO file and flash command paramter to 0083.

The magic message: "NVRAM checksum error"

At next startup, the motherboard works!

Thank you again!

RogerBacon · 02-22-09, 01:24 PM

I'm really sorry to up this topic but i can't contact the 2 individual who managed to get it work (again).

I would really appreciate if someone can give me further explanation (I can't get the 'NVRAM cheksum error') or if someone can make me a modified ISO image. The recovery disk simply restore the BIOS without USB enabled. I tryed with the ISO edit image (frame) and inserting the 0083 bios and with the BIO recovery disk too... I'm probably doing something wrong.

Anyway, if an admin could send an email to Manmachine and Enb141 i would really appreciate it !

manmachine · 02-22-09, 02:25 PM

Dear BogerBacon,

Here is the ISO file which helped me to enable the USB ports again:

http://manmachine.uw.hu/dp45sg_0083.ISO
(Maybe the download will slow).

Write this image to a CD, and boot from it. It will re-start the PC twice. Bios recovery jumper have to be in normal position.

I made this "downgrade" from a higher BIOS version (0102) and cleared the CMOS before, but maybe these facts are not important.

It is waiting at the office for me right now so I'll have some time to play with it tomorrow and tell you if it works. If this does not plug and play immediately and allow me to alter BIOS with a PS/2 keyboard then I'm back to waiting until the DP45SG is back in stock and I have a PS/2 input for the next time I'm a dumbass. WTF, Intel? __________________ Current System: Intel Q6700 2.66GHz Intel DP45SG Socket 775 2GB OCZ PC10600 DDR3 1333 MSI NX500GT 256MB Lite-On iHES106-29 BD (P.O.S.)

Installation failed by an IRQ error, so I tried to disable integrated peripherials step-by-step. I hoped that a simple CMOS clearing will set the whole system into default state. But CMOS jumper simply does nothing! I measured the voltages on three pins. Center pin is on ground (0V), free pin is on +3V like any other motherboards. But if I connect them by the jumper, nothing happens at next startup. I plugged a PCI-USB card into the computer, so my keyboard and mouse work under Vista but every other peripherials that I disabled before in setup don't work. BIOS can not initialize this USB card, so keyboard unusable under booting. I wrote an e-mail to Intel today. (sorry for my English)

manmachine Registered Join Date: Feb 2009	Bad news: it doesn't work. There is a "CMOS" jumper on motherboard, but it is not mentioned in manual or Intel's homepage. There are some words about removing battery, waiting an hour etc. These actions do nothing. It writes "cmos checksum error", "time not set" - but all peripherial stay disabled. Flash updating from pendrive (flash recovery mode enables only one USB port if it detects a pendrive in it) runs perfectly, but also does nothing with bios settings.

vulcanman09 Member Join Date: Aug 2003 Location: ontario, canada	sorry ! i should have also stated , that you should also remove the cmos battry after the green light on mobo stops glowing. process correction. turn off computer. turn off power supply switch wait till green light stops glowing. remove cmos back-up battery. remove normal operation jumper ( do not replace yet ) pins 1 and 2 jumpered wait 10 minutes. ( found this online regarding factory intel boards ) replace cmos back-up battery replace jumper on pins 2 and 3 ( enter the bios settings ) turn on power supply switch. ( on some factory intel boards, after a bios reset, the green light will blink ) fire up the computer. the bios should be reset to factory default settings Last edited by vulcanman09; 02-18-09 at 04:17 PM.

manmachine Registered Join Date: Feb 2009	Dear enb141, I made the boot cd following your method, it has worked perfectly. I updated the bios from 0093 to 0102, the update was successfull. But there is no change in (non) operating of USB. (I have two USB keyboards, so I could try both of them) Intel has answered my e-mail. They wrote, I had to remove battery for 24 hours. I do not hope that it will work. I think, something on my motherboard is dead.

enb141 New Member Join Date: Feb 2009	My question do you had USB keyboard support before or you never had USB keyboard support? The problem with this motherboard is that some keyboards doesn't works, I have three USB keyboards (Logitech Illuminated Keyboard, Mac Keyboard (the new one)) and Logitech Elite Keyboard, and from the three only one works the Old Elite Keyboard so try to use an old USB keyboard specially those that have PS2 to USB Adapter.

enb141 New Member Join Date: Feb 2009	Which of the two methods that I've metion to you was used, the ISO edit or the Recovery BIO?

manmachine Registered Join Date: Feb 2009	I used ISO edit, and it ran without problems.

02-18-09, 06:03 PM	#27
enb141 New Member Join Date: Feb 2009	Weird, ok, do this same thing using ISO Edit, upgrade now to 0108 if still you don't have USB Support go and downgrade to 0083 this one doesn't have ISO on their website but you can use it editing the ISO File with SG0083.BIO on it. I was in the same situation as you were, my USB were not working on OSX so I started to disable LAN, Audio, then Legacy USB and finally USB which give me problems but my solution worked to me, I hope this works for you.

manmachine Registered Join Date: Feb 2009	Dear enb141, Thank you! Thank you! Thank you! Thank you! Thank you! Thank you! Thank you! I made an ISO image using the "frame" of 0102 but I replaced the BIO file and flash command paramter to 0083. The magic message: "NVRAM checksum error" At next startup, the motherboard works! Thank you again! http://nagykrisztian.com/

RogerBacon Registered Join Date: Feb 2009	I'm really sorry to up this topic but i can't contact the 2 individual who managed to get it work (again). I would really appreciate if someone can give me further explanation (I can't get the 'NVRAM cheksum error') or if someone can make me a modified ISO image. The recovery disk simply restore the BIOS without USB enabled. I tryed with the ISO edit image (frame) and inserting the 0083 bios and with the BIO recovery disk too... I'm probably doing something wrong. Anyway, if an admin could send an email to Manmachine and Enb141 i would really appreciate it !

manmachine Registered Join Date: Feb 2009	Dear BogerBacon, Here is the ISO file which helped me to enable the USB ports again: http://manmachine.uw.hu/dp45sg_0083.ISO (Maybe the download will slow). Write this image to a CD, and boot from it. It will re-start the PC twice. Bios recovery jumper have to be in normal position. I made this "downgrade" from a higher BIOS version (0102) and cleared the CMOS before, but maybe these facts are not important.
