IRQ7 Source
Í
Î Determines source for IRQ7 interrupt.
•Disabled
• LPT (default)
•SerialCN8
If set to disabled, IRQ7 may be an input from the
PC/104 bus.
Shadow C000h-
C7FFh
Shadow C800-
CFFFH
Shadow D000-
DFFFh
Í
Î Enables shadowing of the BIOS and memory.
Selections are:
• Enabled: address range is copied (shadowed) to
RAM.
• Disabled: address range remains mapped on the
bus.
In DOS systems, addresses between A0000H and
FFFFFH are usually reserved for devices mapped
on the bus. Accesses to these addresses are slower
than accesses to system memory (RAM). The shad-
ow options copy code from these addresses into
RAM, improving general performance of the sys-
tem.
Segment E000h
Map
Í
Î Selects mapping of segment E000h of memory.
Selections are:
• PC/104 Bus
•BIOSROM
When PC/104 Bus is selected, addresses in segment
E0000-EFFFFh are free for external use.
When BIOS ROM is selected, this segment is
mapped into the on-board BIOS ROM chip. This
selection will cause Setup to be executed at every
boot, whether or not {Delete} is pressed.
Boot Type
Í
Î Selects boot type.
Selections are:
• Standard: Will perform RAM scan/checking
• Quick: Will skip RAM scan/checking
Chipset Error
Í
Î Defines reaction to errors in microprocessor, copro-
cessor, timer, or DMA and interrupt controller ini-
tialization.
ON: prints error warning
OFF: continue without warning
Memory error
Í
Î Defines reaction to errors during memory tests.
ON: prints error warning
OFF: continue without warning
This setting only applies during the following pow-
er-on tests:
• memory size (base and extended)
• memory test (base and extended)
