Thanks for your replies... It's been a messy day with this server. HP shipped it with only one of the two RAID hard disks, and I went ahead and prepped it, thinking I could just add the other disk later and synch it up. Wrong - with this particular SATA RAID controller, the RAID configuration wipes out all existing data on the disks. That's how I discovered that the drives are currently using the controller as a standard atapi drive. Anyway, it's an HP ML150 G3 server with an on-board SATA RAID controller. The textsetup.oem file calls it: "Adaptec SATA Drive v1.00 (Windows 32 bit for 2000/XP/2003)" I figured if it was being loaded, I could press F6 anyway, and before I put the disk in the A: drive it would show the drivers already loaded and offer to load more. However, the list of drivers loaded was empty - the atapi driver wasn't there either. I'm wondering if the RAID actually has to be enabled in order for this thing to reject the atapi drive and look for something else... No matter what, I will need to install the driver. I'm trying to do it without having to try it first (using the nLite CD) and then running out to find a floppy drive just to install the driver... This nLite looks great for this sort of thing - I'm eager to play around with it and see what it can do. While the integrated driver feature brought me here, there are lots of interesting features... **** UPDATE **** I figured I had to reformat anyway, so I ran through the install. While formatting, it said "Formatting DISK 1 on atapi..." or something to that affect. So, I guess these disks appear like a standard disk drive unless the RAID is created first in the BIOS. I'll know more when I get the second drive. Thanks for your replies...
