Specifications

5.3.5.5 Hard Drive 1
This option must be configured to determine drive-specific parameters. Choose
from types 1 through 47. If hard drive 1 is not installed, then select "Disabled."
User-definable types 2, 3, 48, and 49 require you to enter specific parameters
(cylinders, heads, precompensation, landing zone, and sectors). You can select
either types 2 and 3 or types 48 and 49 as user definable. IDE hard drives are
usually selected as "Drive Type 1." Because certain operating systems do not
recognize BIOS drive type parameters above type 47, the parameters for drive
types 48 and 49 should be aliased to types 2 and 3 using this option.
5.3.5.6 Hard Drive 2
This option is the same as the hard drive 1 option.
5.3.5.7 Parallel Port and Serial Ports
The system logically assigns LPTx and COMx names to:
• Parallel ports in the address order 378h and 278h
• Serial ports in the address order 3F8h, 2F8h, 3E8h, and 2E8h
This occurs during each boot process. For example, if you are using the DOS
operating system and you disable the serial port that is assigned to 3F8h as
COM1, during the next boot cycle the system will reassign the name COM1 to
the next enabled serial port in the sequence.
5.3.5.8 CPU Speed
This option determines the speed used by the system each time you turn it on
or reboot it. Fast is the normal setting for CPU speed. The fast setting enables
operation at the rated speed. Slow (equivalent to 8 MHz) is used to reduce the
effective CPU speed to be compatible with some speed-dependent application
programs (mostly games). If an application program does not run correctly at
full speed, try changing the CPU speed to slow.
5.3.6 Examine Required Switches
This menu item allows you to display the switches and jumpers that must be
set manually on the system board and on any expansion board. This menu
item also lists applicable software drivers that need to be installed.
If you need to set switches or jumpers, make sure you write them down before
you exit the SCU and power down the system.
