Write Protect Boot Sector Disables the write function only on the boot sector
of the diskette or hard disk drive.
Normal Allows the diskette or hard disk drive to function normally. This is the
default setting.
Onboard Floppy Disk Controller This parameter allows you to enable or
disable to onboard floppy disk controller chipset. When set to Enabled, the
controller enables the diskette drive on your computer. When set to Disabled,
the controller deactivates the drive but simultaneously frees IRQ 6 which is
normally assigned to the diskette drive. You may then assign IRQ 6 to another
device.
Onboard IDE Primary Channel This parameter allows you to enable or
disable the onboard IDE primary channel controller. Setting this parameter to
Enabled lets you use the primary IDE connector (IDE 1) to connect up to two
IDE drives. Setting to Disabled deactivates IDE 1 but frees IRQ 14 for the use
of other devices. The default setting is Enabled.
Onboard IDE Secondary Channel This parameter allows you to enable or
disable the onboard IDE secondary channel controller. Setting this parameter
to Enabled lets you use the secondary IDE connector (IDE 2) to connect up to
two IDE drives. Setting to Disabled deactivates IDE 2 but frees IRQ 15 for the
use of other devices. The default setting is Enabled.
Memory/Cache Options
The Memory/Cache Options menu allows you to configure the Level 1 and
Level 2 caches. Enabling the cache parameters optimize system performance.
Some older applications, however, may not run properly with the caches
enabled. Set the parameters to Disabled when you run these applications.
Disabling the caches will degrade system performance.
Internal Cache This parameter enables or disables the internal cache
memory. The default setting is Enabled.
External Cache This parameter enables or disables the external cache
memory. The default setting is Enabled.
Memory Parity Mode This parameter enables or disables the memory ECC
check function. The default setting is Disabled.
Memory Configuration This parameter shows the installed memory
configuration information.
