VL-HD1 Hard Disk Cards
This manual describes how to configure VersaLogic CPU cards to work properly with
VersaLogic hard disk drives.
VersaLogic DOS-based processor cards require that the disk drive parameters be loaded into
CMOS before the IDE disk drive controller will function properly.
Hard Disk Parameters
Hard disk drive parameters are set in CMOS, and are referred to by the DOS BIOS. Changes to
CMOS are accomplished by pressing the DEL key during the bootup process, which opens the
BIOS Setup screen. From the Setup screen you can change a variety of hardware configurations,
including the hard disk drive parameters.
We recommend using the "Auto IDE Detect" function on the BIOS Setup screen to have the CPU
card automatically read the parameters from the attached IDE drive.
VersaLogic hard disk drives use disk type numbers 47 and 48. The hard disk is usually declared
as drive C:. The following table lists all configurations currently in use by VersaLogic.
