This option lets you reserve system memory area for
special ISA cards. Chipset accesses code/data of these
area from the ISA bus directly, normally it is for memory
mapped I/O card.

For some old I/O chips, when there is an I/O command
finished, the device needs a specified amount of time
(recovery time) before next I/O command can be started.
Because of new generation CPU and mainboard chipset, the
assertion of I/O command is getting faster, and sometimes
shorter than specified I/O recovery time of old I/O devices.
This item delays 8-bit I/O command by count of ISA bus
clock, if you find any unstable 8-bit I/O card, you may try to
extend the I/O recovery time by setting of this item. The
BIOS default value is 4 system clocks. If set to Disabled,
the chipset will insert 3.5 system clocks.

The same as 8-bit I/O recovery time. This item delays 16-bit
I/O command by count of ISA bus clock, if you find any
unstable 16-bit I/O card, you may try to extend the I/O
recovery time by setting of this item. The BIOS default value
is 1 system clocks . If set to Disabled, the chipset will auto
insert 3.5 system clocks.
Chipset --> DRAM Timings

70ns
The selections for this item are 60ns, 70ns, and Manual. If
you select either 60ns or 70ns, the DRAM Timing subitems
become non-configurable since BIOS automatically sets the
values. Select Manual if you want to specify your own item
settings. The BIOS default is 60ns.
