Hey,
I have an older p-III system running XP pro where the HDs will not come out of PIO mode. I have tried all of the various BIOS tweaks, removing the controller from device manager, etc. This is killing the performance. My daughter uses this for surfing, email, etc. Nothing major. Anyway, I think the onboard IDE controller is dying. I have a Promise Ultra 100 TX-2 IDE controller card that I can put into the machine, but I cannot figure out how to make the PC boot from the new controller. I removed the HDs from the existing controller and can see the drive in the Promise BIOS screen at boot-up, but cannot get it to boot. I tried disabling the onboard controller, but still nothing. Anyone have any ideas? Thanks, Bobby
