Configuring an MFM Drive
If configuring an old MFM hard disk drive, you must know the drive parameters (number of heads,
number of cylinders, number of sectors, the starting write precompensation cylinder, and drive
capacity). Choose Type and choose the appropriate hard disk drive type (1 - 46). The old MFM
hard drive types are listed on appendix A. If the drive parameters of your MFM drive do not match
any drive type listed, select User in the Type field and enter the drive parameters on the screen that
appears.
User-Defined Drive
If you are configuring a SCSI drive or an MFM, RLL, ARLL, or ESDI drive with drive parameters
that do not match drive types 1-46, you can select the User in the Type field. You must then enter
the drive parameters on the screen that appears. The drive parameters include:
Cylinder (number of cylinders),
Hd (number of heads),
WP (starting write precompensation cylinder),
Sec (number of sectors),
Size (drive capacity).
Configuring IDE Drives
If the hard disk drive to be configured is an IDE drive, select the appropriate drive icon (Pri Master,
Pri Slave, Sec Master, or Sec Slave). Select the IDE Detect icon to automatically detect all drive
parameters.
AMIBIOS automatically detects the IDE drive parameters (including ATAPI CD-ROM drives) and
displays them. Click on the OK button to accept these parameters Or you can set the parameters
manually if you are absolutely certain that you know the correct IDE drive parameters.

AMIBIOS to automatically find the PIO mode that the IDE drive being configured uses. If you
select 0-5 you must make absolutely certain that you are selecting the PIO mode supported by
the IDE drive being configured.
Configuring a CD-ROM Drive
Select the appropriate drive icon (Pri Master, Pri Slave, Sec Master, or Sec Slave). Choose the
Type parameter and select CDROM. You can boot the computer from a CD-ROM drive. You can
also choose Auto and let AMIBIOS automatically set the correct drive parameters.
