After I upgraded to XP, I have two hard drives completely missing and undetected. The two hard drives are older guys hanging off of a Promise Ultra33 PCI board. The Hcl says it is compatible, the Promise guys say it is compatible. When the system was running Me there was no issue. When the system boots up there is a screen just after the bios sets up that shows the Promise board initializing. In Windows XP it's as if the hardware and hard drives don't even exist. Any ideas? No amount of mucking or scanning for hardware makes them appear.
