BIOS flashers might not work in Safe Mode. Safe Mode prevents a bunch of drivers from loading, and other stuff, that's why it's called Safe Mode. No probably faulty drivers, no errors. But among those drivers, might be the one who takes care of BIOS flashing (WinFlash.sys and WinFlash64.sys, installed by the HP tool). If those don't load, they will drop an error, that the tool might identify as "not compatible".
The same CyanogenMod disclaimer as before.
That exe file has a 513.ROM inside. To rip it, "unzip" it like you would do with any other .rar or .7z, using your file archiver of preference. I like 7z. You only need the ROM file. Ignore the winflash files and the rtf file. Those, you don't need.
1) Create a bootable DOS USB drive, for example, using this guide (
http://www.pendrivelinux.com/boot-dos-from-usb/).
2) Rename the BIOS file (513.ROM) to bios.bin, and copy that to the pendrive. Copy the awdflash I linked before too.
3) Create a notepad file called autoexec.bat in the root of the pendrive (e.g. X:/). It's autoexec.bat. Not autoexec.bat.txt or anything like that. The extension is BAT like Batman.
4) Copy this into the file and save the file. Remember, autoexec.bat like Batman.
Code:
@echo off
awdflash.exe bios.bin old.bin /py /sy /cc /cp /cd /sb /r
5) Restart your computer and boot from the USB. With a bit of luck you'll see a DOS shell and AwardFlash working. If not, try to call autoexec.bat from that shell.
6) If it works, gratz! If you get any errors, please copy all the info it gives and reply back.
We are not flashing the bootblock, so it won't be dead if you kill something. But, please, try not to.
