Sounds like you're working with an AT class machine (as opposed to an XT class machine). The BIOS on the mother board contains the rountines for running the hard disk. The problem you running into is that the controller *also* has its own BIOS...so what you need to do is in the setup program, specify "no hard disk" (which disables the motherboard disk BIOS routines) to allow the controller BIOS to function properly... Another alternative is to get a controller that doesn't have an on board BIOS (not sure if there are any RLLs without on board BIOS). I would suggest that you go to your local library or book store and pick up a book on repairing and upgrading PC's...I don't know the author, but a book I've used goes by the title "Repairing and Upgrading your PC" which was available at walden software/books...

Some BIOSs don't have the correct options for them. My Pheonix 386SX BIOS is an example. Kevin Meis att!drutx!kmeis

The disk controller bios still looks at an AT's CMOS RAM to determine the drive type number. I use a 1006-SR2 also and I had to set the drive number types to the type that matched the table in the hard disk controller bios. The tables between controller and mother- board bios (AMI) did not match. It seems like I tried the user selectable parameters and didn't have much luck. However I did find parameters 'close enough' in the disk controller bios table. Cliff Koch
