Adaptec SBC-596, SBC-599 manual Advanced Host Adapter Settings, Host adapter Bios is enabled

Page 85

Setting this option to yes reduces the load on your computer’s power supply by allowing the host adapter to start SCSI devices one-at-a-time when you boot your computer. When set to No, the devices are allowed to start at the same time. Most devices require you to set a jumper before they can respond to this command.

Note: If the Send Start Unit Command is set to yes for many devices, the boot time will vary depending on how long it takes each drive to start.

Advanced Host Adapter Settings

The advanced host adapter settings should not be changed unless absolutely necessary.

nPlug and Play SCAM Support - This option determines whether the SCSI automatically assigns SCSI Ids to attached SCSI Devices that support the SCAM protocol. The default setting is Disabled.

Most non-SCAM devices tolerate SCAM protocol, so you can enable this option even for non-SCAM devices. In rare cases, an old SCSI-1 device may not tolerate SCAM and may cause the computer to hang or operate erratically. If this happens, disable this option.

nHost Adapter BIOS – This option enables or disables the host adapter BIOS. The default setting is Enabled.

Note:	Several SCSISelect options are not valid unless
	the host adapter BIOS is enabled.

If you are booting from a SCSI disk drive connected to the host adapter, the BIOS must be enabled. You should disable the host adapter BIOS if the peripherals on the SCSI bus (for example, CD-ROM drives) are all controlled by device drivers and do not need the BIOS.
