Choose these items to configure the hard disk drive named in the
option. When you click on an item, the following parameters are listed:
Type, LBA Mode, Block Mode, PIO Mode, and 32Bit Mode. All
parameters relate to IDE drives except Type.
!" Configuring an MFM Drive
If configuring an old MFM hard disk drive, select Type and choose
the appropriate hard disk drive type (1 - 46). Refer to Appendix B
for the Hard Disk Drive types available. If the MFM drive
parameters 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
When configuring SCSI drive or an MFM, RLL, ARLL, or ESDI drive
with drive parameters that do not match drive types 1-46, select
User in the Type field. Enter the drive parameters on the screen
that appears.
!" Configuring IDE Drives
If the hard disk drive is an IDE drive, select the appropriate drive
icon (Pri Master, Pri Slave, Sec Master, or Sec Slave). Choose the
Type parameter and select Auto. AMIBIOS automatically detects
the IDE drive parameters and displays them. Click on the OK button
to accept these parameters.
LBA Mode - LBA (Logical Block Addressing) is a new method of
addressing data on a disk drive. In the ST506 (MFM) ISA hard disk
drive standard, data is accessed via a Cylinder-Head-Sector format.
Because the number of cylinders, disk drive heads, and sector is
limited, an MFM drive can hold a maximum of 528 MB of data. In
LBA mode, the maximum drive capacity is 8.4 GB.
If LBA Mode is disabled in AMI BIOS Setup, AMI BIOS uses the
physical parameters of the hard disk and AMIBIOS does not
translate parameters. The operating system that uses the
parameter table will only see 528 MB hard disk space even if the
hard disk is greater than 528 MB.
