Advanced Configuration Options

Note:
Do not change the Advanced Host Adapter Settings
unless absolutely necessary.
Plug-and-Play SCAM Support—When set to Enable, the SCSI
card automatically assigns SCSI IDs to SCSI peripherals that
support the SCAM protocol (see SCSI IDs on page 1). The
default is Disable, but you can set it to Enable even if you
have a non-SCAM peripheral.
Reset SCSI Bus at IC Initialization—When set to Enable, the
SCSI card generates a SCSI bus reset during its power-on ini-
tialization and after a hard reset.
Extended BIOS Translation for DOS Drives > 1 GByte—
When set to Enable, provides an extended translation scheme
for SCSI hard disks with capacities greater than 1 GByte. This
setting is necessary only for MS-DOS 5.0 or above; it is not
required for other operating systems, such as NetWare or
UNIX.The extended translation scheme supports disk drives
as large as 8 GBytes.
To partition a disk larger than 1 GByte controlled by the SCSI
card BIOS, use the MS-DOS Fdisk command.
Caution:
translation scheme.
Host Adapter BIOS (Configuration Utility Reserves BIOS
Space)—Enables or disables the SCSI card BIOS.
Set to Enable if you boot from a SCSI disk drive connected
to the SCSI card.
Set to Disable if the peripherals on the SCSI bus (for exam-
ple, CD-ROM drives) are controlled by software drivers
and do not need the BIOS.
Support Removable Disks Under BIOS as Fixed Disks—
Determines which removable-media drives are supported by
the SCSI card BIOS. Choices are as follows:
