Floppy Drive Swap
Setting to
Enabled
will swap floppy drives A: and B:.
Floppy Drive Seek
This setting causes the BIOS to search for floppy disk drives at boot time.
When enabled, the BIOS will activate the floppy disk drives during the boot
process: the drive activity light will come on and the head will move back and
forth once. First A: will be done and then B: if it exists. Setting options:
Disabled
,
Enabled
.
Security Option
This specifies the type of AMIBIOS password protection that is implemented.
Setting options are described below.
Boot OS/2 for DRAM > 64MB
This allows you to run the OS/2
®
operating system with DRAM larger than
64MB. When you choose
No
, you cannot run the OS/2
®
operating system
with DRAM larger than 64MB. But it is possible if you choose
Yes
.
Internal Cache
Cache memory is additional memory that is much faster than conventional
DRAM (system memory). When the CPU requests data, the system transfers
the requested data from the main DRAM into cache memory, for even faster
access by the CPU. The setting controls the internal cache (also known as L1
or level 1 cache). Setting options:
Disabled, WriteBack, WriteThru
.
WriteBack
&
WriteThru
refer to the cache’s write policy, which determines how it handles
writes to memory locations that are currently being held in cache. The
WriteBack
cache policy will produce the best performance.
System BIOS Cacheable
Selecting
Enabled
allows caching of the system BIOS ROM at F0000h-FFFFFh,
resulting in better system performance. However, if any program writes to this
memory area, a system error may result. Setting options:
Enabled, Disabled
.
