ECS P5SD-B Plus Manual page 20

External Cache
This mainboard is installed with 512K of external (level 2) cache memory to improve
performance. Leave this item at the default value Enabled for better performance.
Quick Power On Self Test
You can enable this item to shorten the power on testing and have your system start up a
little faster. You might like to enable this item after you are confident that your system
hardware is operating smoothly.
Boot Sequence
This item defines where the system will look for an operating system, and the order of
priority. You can boot an operating system from many locations including a SCSI device, a
ZIP drive, a floppy diskette drive or an LS-120 high-capacity diskette drive.
Swap Floppy Drive
If you have two floppy diskette drives in your system, this item allows you to swap around
the assigned drive letters so that drive A becomes drive B, and drive B becomes drive A.
Boot Up NumLock Status
This item defines if the keyboard Num Lock key is active when your system is started.
Gate A20 Option
This option provides compatibility with older software written for the 286 processor. Leave
this item at the default value Fast.
Memory Parity/ECC Check
This mainboard supports memory with a parity bit or memory with error correction code,
so leave this item at the default value of Enabled so that potential memory errors can be
eliminated.
Security Option
If you have installed password protection, this item defines if the password is required at
system start up, or if it is only required when a user tries to enter the setup utility.
IDE Second Channel Control
If you have more than one hard disk connected to the IDE channel, set this item to enabled
to improve the access time to the disks. If you only have one hard disk drive installed,
disable this item.
PCI/VGA Palette Snoop
This item is designed to overcome some problems that can be caused by some non-
standard VGA cards. This board includes a built-in VGA system that does not require
palette snooping so you must leave this item disabled.
OS Select For DRAM > 64 MB
This item is only required if you have installed more than 64 MB of memory and you are
running the OS/2 operating system. Otherwise, leave this item at the default Non-OS2.
Video BIOS Shadow
This item allows the video BIOS to be copied to system memory for faster performance.
XXXXX-XXXXX Shadow
These items allow the BIOS of other devices to be copied to system memory for faster
performance.
