HELP: Abit KT7A Raid win2k shutdown woes

[Vlad]

Hey guys I just got a Abit KT7A raid +Tbird combo from Frys for $329 and Everything is working great, except it takes a really long time for Win2k to shutdown or restart.(I used to have a similar problem with Abit p2b-d untill I got its ACPI fixed) What is happening?
Also the board recognized the cpu as 7.5x100 by default(running at 750mhz) I had to change it to 7.5x137 to run at 1 Ghz. Is that right or was my cpu mismarked?
