that IRQ. If you install a legacy ISA card that requires a unique IRQ,
you must set the field for that IRQ to “Legacy ISA”. Say for example
that you install a legacy ISA card that requires IRQ10. You must then
set “IRQ-10 assigned to :” as “Legacy ISA”.
3.7.2 DMA-x assigned to : PCI/ISA PnP
These fields indicate whether or not the displayed DMA channel for
each field is being used by a legacy (non-PnP) card. Two options are
available: PCI/ISA PnP or Legacy ISA. The first option, the default
setting, indicates that the displayed DMA channel is not used to
determine if an ISA card is using that channel. If you install a legacy
ISA card that requires a unique DMA channel, you must set the field
for that channel to “Legacy ISA”.
3.7.3 Used MEM base addr : N/A
This field allows you to set the base address and block size of a legacy
ISA card that uses any memory segment within the C800H and DFFFH
address range. If you have such a card, select a used base address
from the six available options. The “Used MEM base addr” field will
then appear for selecting the block size. If you have more than one
legacy ISA card in your system that needs to use this address range,
you can increase the block size to either 8 K, 16 K, 36 K or
64 K.
3.8 Load BIOS Defaults
“LOAD BIOS DEFAULTS” indicates the most appropriate values for
the system parameters to achieve maximum stability. These default
values are loaded automatically if the stored record created by the
setup program becomes corrupted (and therefore unusable).
3.9 Load Setup Defaults
“LOAD SETUP DEFAULTS” loads the values required by the system
for maximum performance.
