Extended Translation for Drives > 1 GByte

This option allows you to enable or disable extended translation

for SCSI hard disks with a capacity greater than 1 GByte. The

default setting is enabled. Appendix D, Disk Drives Over 1

Gigabyte discusses the extended translation feature in detail.

If this option is enabled, the following translation schemes are used:

•

SCSI hard disks ≤ 1 GByte use a translation scheme of 64

heads, 32 sectors per track

•

SCSI hard disks > 1 GByte use a translation scheme of 255

heads, 63 sectors per track

Note

Enabling this option for operating systems that do not need

extended translation (e.g., NetWare

386 and UNIX

) can

cause drive failure and/or data loss)

Support More than Two Drives

This option allows you to enable or disable BIOS support for more

than two SCSI hard disks (supported by DOS 5.0 and above). The

default setting is disabled.

SCSI Device Configuration

SCSI Device Configuration allows you to customize the configura-

tion of each SCSI device connected on the SCSI bus. When this

option is selected, a screen similar to Figure 3-13 is displayed. All

SCSI IDs are displayed on the screen even if no SCSI device is

attached; however, to configure a specific SCSI device, you will

need to know which SCSI ID corresponds to that SCSI device.

Use the cursor keys to move between options. To toggle values for

each option, press the Enter key.
