table above. This value will be lower than the usable drive capacity.

In a few situations, none of the drive types specified in your BIOS setup program will match your drive, and the setup program will not provide an opportunity to specify a custom drive type. In this case, consider the third option described above — allowing your ST9235 family drive to mimic one of the BIOS-supported drive types. During the BIOS setup process, simply select a drive type with a capacity that is less than or equal to the drive’s BIOS calculated capacity listed in the table on page 6. This drive type should have no more than 16 read/write heads or 63 sectors per track. In addition, the total number of sectors for that drive type (listed in the setup program) should not exceed the number of cylinders times the number of read/write heads times the number of sectors per track. In other words:

Total sectors per drive ≤

(No. cylinders) × (No. read/write heads) × (No. sectors per track)

BIOS compatibility recommendations

The ST9235 family drives are AT interface compatible drives, which conform to ATA specifications. The host system BIOS must provide support for the AT interface command set. Consult the system documentation for information on the AT interface within your system. Several key compatibility issues are discussed below.

In accordance with ATA specifications, the BIOS must reset any emulation/translation parameters after a hard reset is received from the host.

In some configurations, the ST9235 family AT interface drives supply 11 bytes of Error Correction Code (ECC) with the Read Long and Write Long commands. Depending on the drive type,
