Chapter 8: Configuring the Adaptec SCSI Card with SCSISelect ● 38 Advanced Configuration Options ! Caution: Do not change the Advanced Configuration Options unless absolutely necessary and you thoroughly understand the consequences of the change. ● Reset SCSI Bus at IC Initialization-(Default: Enabled) When set to Enabled, the BIOS resets the SCSI bus at POST time and then waits two seconds before scanning the bus for SCSI devices. If this option is disabled, the SCSI card BIOS does not issue a SCSI reset and there is no two-second delay. ● Display Messages during BIOS Initialization-(Default: Enabled) When set to Enabled, the SCSI card BIOS displays the Press for SCSISelect (TM) Utility! message on your screen during system bootup. If this setting is disabled, you can still invoke the SCSISelect Utility by pressing after the SCSI card BIOS banner appears. ● Extended INT 13 Translation for DOS Drives > 1 GByte-(Default: Enabled) When set to Enabled, provides an extended translation scheme for SCSI hard disks with capacities greater than 1 GB. This setting is necessary only for current versions of MS-DOS; it is not required for other operating systems, such as NetWare or UNIX. ! Caution: Changing the translation scheme destroys all data on the drive. Be sure to back up your disk drives before changing the translation scheme. ● Post Display Mode-(Default: Verbose) During POST, the amount of information displayed depends on the mode. The following modes are available: ● Verbose-The results of the SCSI bus scan are displayed, but the results of the PCIe bus scan are not displayed. ● Silent-Nothing is displayed about POST, not even the Adaptec banner. However, error messages are displayed if there is a problem on the SCSI bus or SCSI devices. ! Caution: Setting this feature to Silent completely disables the messages displayed by the Adaptec Ultra320 SCSI card during the restart of the system. You will have to remember where in the POST cycle of the BIOS the Press Ctrl-A to enter SCSISelect message was displayed, and press Ctrl-A at that time to get into SCSISelect. If you press Ctrl-A too early or too late, you will not be able to enter into the card's setup. ● Diagnostic-The PCI and SCSI bus scan results are displayed separately. There is a pause between PCI and SCSI scans. ● SCSI Card INT 13 Support-(Default: Enabled) This option controls the state of the BIOS at POST time. The following settings are available: ● Enabled-Supports INT 13 for booting from a SCSI disk drive connected to the SCSI card. If you use this option, the following options are available: ● Extended INT 13 Translation for DOS Drives > 1 GB ● Support Removable Disks Under INT 13 as Fixed Disks ● Disabled:NOT Scan-Set to this option if all the devices on the SCSI bus (for example, CD-ROM drives) are controlled by software drivers and do not need the BIOS, and you do not want the BIOS to scan the SCSI bus. SCSISelect remains available if needed.

Advanced Configuration Options
Caution:
Do not change the Advanced Configuration Options unless absolutely necessary and
you thoroughly understand the consequences of the change.
●
Reset SCSI Bus at IC Initialization
—(Default: Enabled) When set to Enabled, the BIOS
resets the SCSI bus at POST time and then waits two seconds before scanning the bus for
SCSI devices. If this option is disabled, the SCSI card BIOS does not issue a SCSI reset and
there is no two-second delay.
●
Display <Ctrl> <A> Messages during BIOS Initialization
—(Default: Enabled) When set
to Enabled, the SCSI card BIOS displays the Press <Ctrl> <A> for SCSI
Select
(TM) Utility!
message on your screen during system bootup. If this setting is disabled, you can still
invoke the SCSI
Select
Utility by pressing <Ctrl> <A> after the SCSI card BIOS banner
appears.
●
Extended INT 13 Translation for DOS Drives > 1 GByte
—(Default: Enabled) When set to
Enabled, provides an extended translation scheme for SCSI hard disks with capacities
greater than 1 GB. This setting is necessary only for current versions of MS-DOS; it is not
required for other operating systems, such as NetWare or UNIX.
Caution:
Changing the translation scheme destroys all data on the drive. Be sure to back
up your disk drives before changing the translation scheme.
●
Post Display Mode
—(Default: Verbose) During POST, the amount of information
displayed depends on the mode. The following modes are available:
●
Verbose
—The results of the SCSI bus scan are displayed, but the results of the PCIe
bus scan are not displayed.
●
Silent
—Nothing is displayed about POST, not even the Adaptec banner. However,
error messages are displayed if there is a problem on the SCSI bus or SCSI devices.
Caution:
Setting this feature to Silent completely disables the messages displayed by the
Adaptec Ultra320 SCSI card during the restart of the system. You will have to remember
where in the POST cycle of the BIOS the Press Ctrl-A to enter SCSI
Select
message was
displayed, and press Ctrl-A at that time to get into SCSI
Select
. If you press Ctrl-A too early
or too late, you will not be able to enter into the card’s setup.
●
Diagnostic
—The PCI and SCSI bus scan results are displayed separately. There is a
pause between PCI and SCSI scans.
●
SCSI Card INT 13 Support
—(Default: Enabled) This option controls the state of the BIOS
at POST time. The following settings are available:
●
Enabled
—Supports INT 13 for booting from a SCSI disk drive connected to the SCSI
card. If you use this option, the following options are available:
●
Extended INT 13 Translation for DOS Drives > 1 GB
●
Support Removable Disks Under INT 13 as Fixed Disks
●
Disabled:NOT Scan
—Set to this option if all the devices on the SCSI bus (for example,
CD-ROM drives) are controlled by software drivers and do not need the BIOS, and
you do not want the BIOS to scan the SCSI bus. SCSI
Select
remains available if needed.
