I'm using the KG-7 Raid mobo. With XPpro, XP used it's own HPT drivers when I installed. I'm not actually using the mobo for Raid but I AM using the Raid (IDE3 & 4) for my two hard drives (soon to be three).
My CD writer and DVD player are masters on IDE1 & 2.
This setup works very well with no problems.
I multi-boot between 98SE, ME and XPpro.
With 98SE and ME I use the drivers that came with the KG-7.
