drive types your BIOS supports. Another method is to run the FINDTYPE.EXE utility program, available from Seagate Techni- cal Support services (on the SeaBOARD BBS) as described in Appendix C.

The methods used to configure system BIOS vary from system to system. In many cases you can run a setup program from the DOS prompt. In other cases, you must initiate BIOS setup by pressing certain keys while the system is booting up.

Within the setup program, there are three possible ways that you can specify your drive type:

Match your drive specifications (from the table below) with those of a drive type specified in the setup program.

Specify a custom or user-defined drive type in the setup program, then manually enter your drive specifications from the table below.

Select specifications lower than those required for your drive, and allow your drive to mimic the drive type selected.
