IOWA-MARK Half-size CPU Card
Use the Bank Interleave option to specify how multiple modules communicate with each
other. Interleaving enables access to a second memory bank when the first memory bank
is being accessed. The following configuration options are available:
Disabled (D
EFAULT
)
2 Bank
4 Bank
Memory Hole [Disabled]
Use the Memory Hole option to reserve memory space between 15MB and 16MB for ISA
expansion cards that require a specified area of memory to work properly. If an older ISA
expansion card is used, please refer to the documentation that came with the card to see if
it is necessary to reserve the space.
Disabled (D
EFAULT
) Memory is not reserved for ISA expansion cards
Enabled Memory is reserved for ISA expansion cards
P2C/C2P Concurrency [Enabled]
Use the P2C/C2P Concurrency option to enable bi-directional data transmission between
the PCI bus and the CPU.
Disabled Data between the PCI and CPU can only be transferred
in one direction at a time.
Enabled (D
EFAULT
) Data between the PCI and CPU can be transferred in
both directions at the same time.
System BIOS Cacheable [Disabled]
Use the System BIOS Cacheable option to enable 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.
