This option allows you to enable or disable extended translation for SCSI hard
disks with a capacity greater than 1 GByte. It is only valid if the SCSI controller
BIOS is enabled. The default factory setting is Disabled.
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

See the section “Disk Drives Over 1 Gbyte” in this chapter, for more information
on this option. This option should be left Disabled for most operating systems
except DOS/Windows.
