BIOS Features

HDD Sequence SCSI/IDE First (IDE)
When using both SCSI and IDE hard disk drives, IDE is always the boot disk using
drive letter C (default setting of IDE). This field allows a SCSI hard disk drive to be
the boot disk when set to SCSI. This allows multiple operating systems to be used on
both IDE and SCSI drives or the primary operating system to boot using a SCSI drive

Boot Sequence (A,C)
This field determines where the system looks first for an operating system. Options
are A,C; C,A; A,CDROM,C; CDROM,C,A; D,A; E,A; F,A; C only; LS/ZIP, C; LAN,A,C;
and LAN,C,A. The setup default setting, A, C, is to check first the floppy disk and then
the hard disk drive.
Boot Up Floppy Seek (Disabled)
When enabled, the BIOS will seek drive A one time.
Floppy Disk Access Control (R/W)
This allows protection of files from the computer system to be copied to floppy disk
drives by allowing the setting of Read Only to only allow reads from the floppy disk
drive but not writes. The setup default R/W allows both reads and writes.
IDE HDD Block Mode Sectors (HDD MAX)
This field enhances hard disk performance by making multi-sector transfers instead
of one sector per transfer. Most IDE drives, except older versions, can utilize this
feature. Selections are HDD MAX, Disabled, 2, 4, 8, 16, and 32.
HDD S.M.A.R.T. capability (Disabled)
This allows the enabling or disabling of the S.M.A.R.T. (Self-Monitoring, Analysis
and Reporting Technology) system which utilizes internal hard disk drive monitor-
ing technology. This feature is normally disabled because system resources used in
this feature may decrease system performance.
PS/2 Mouse Function Control (Auto)
Auto allows the BIOS to detect the PS/2 mouse on bootup. If detected, IRQ12 will
be used for the PS/2 Mouse. If not detected, IRQ12 will be reserved for expansion
cards. Enabled will always reserve IRQ12 for devices on the PS/2 mouse port.
OS/2 Onboard Memory > 64M (Disabled)
When using OS/2 operating systems with installed DRAM of greater than 64MB,
you need to Enable this option otherwise leave this on the setup default of Disabled.

PCI/VGA Palette Snoop (Disabled)
Some display cards that are nonstandard VGA such as graphics accelerators or MPEG
Video Cards may not show colors properly. The setting Enabled should correct this
problem. Otherwise leave this on the setup default setting of Disabled.
