  That will work with an XT type controller which has the drive parameters
on the card, but not an AT.  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.
