gamer, yeah if you set it to use the basic microsoft driver, not the manufactureres one, i went trhough this once with 2K redid the motherboard and it failed, then checked up on it and found that ide controllers were different and thats one thing windows isnt able to redetect it seems,.
i'd imagine since they are first load, so i put the old motherboard back and reset the drivers back to the standard ide divers, changed back to the new motherboard and installed the bus mastering drivers for the new MB.
this is what you will get

It doesn't list the solution i gave, but I just checked my XP and it does allow you to select "standard dual channel ide" drivers when you do the hardware update drivers, let me pick me own.

a quick scan of google will show you its a common problem
You might have to change you Hal type as well, the first entry in the list usually, typically its the same, but it might change, its the motherboard type, single, dual, acpi etc
Its possible that XP has something new that doesn't allow it to go as smoothly as 2K but i doubt it, since windows XP has to be able to boot on a generic system the "Dual standard ide" drivers should work just fine, i'm thinking product activitation, but with a matching Hal and the default ide driver you should be fine.
