Figure 7-4 BIOS: Advanced Chipset Setup

Automatic Configuration

If selecting a certain setting for one BIOS Setup option determines the settings for one or more other BIOS Setup
options, the BIOS automatically assigns the dependent settings and does not permit the end user to modify these
settings unless the setting for the parent option is changed. Invalid options are grayed and cannot be selected.

AT Bus Clock

This option sets the polling clock speed of ISA Bus (PC/104).

NOTE:

1. PCLK means the CPU inputs clock.
2. Acrosser recommends user setting at the range of 8MHz to 10MHz.

Memory Parity Check

This option

Enables

or

Disables

parity is error checking for all system RAM. This option must be

Disabled

if the

used DRAM SIMMs are 32-bit but not 36-bit devices.

Memory Hole at 15-16 M

This option specifies the range 15MB to 16MB in memory that cannot be addressed on the ISA bus.

ISA I/O Recovery
ISA I/O Recovery Time

These options specify the length of the delay (in BUSCLK) inserted between consecutive 8-bit/16-bit I/O
operations.
