HOT-555 User's Manual 23
DRAM Read Burst (EDO/FP)
This category set the EDO/FP DRAM Read Burst Timing. The timing
used depends on the type of DRAM (EDO burst mode or standard fast page
mode) on a per-bank basis. The options are
x222/x333
,
x333/x444
, and
x444/x444
.
DRAM Write Burst Timing
This category set the DRAM Write Burst Timing. The timing used depends
on the type of DRAM (standard page mode or EDO burst mode) on a per-
bank basis. The options are
x4444
,
x3333
, and
x2222
.
Fast MA to RAS# Delay CLK
This category is used to set Fast MA (Memory Address) to RAS# Delay
which control DRAM Row Miss timings
Fast EDO Path Select
This category is used to defined fast path is selected for CPU to DRAM
read cycles for the leadoff, the options are "
Enable
" or "
Disable
".
Refresh RAS# Assertion
This category is used to set the number of clocks RAS# is asserted for
Refresh cycles.
SDRAM (CAS Lat/RAS-to-CAS)
This category is used to set CAS# Latency and RAS# to CAS# clock for
SDRAM. If SDRAMs absent, this category will not show up.
ISA Clock
This category allows the user to set ISA clock that divide from PCI clock by
3 or by 4. For example, if 166MHz Pentium processor is used, PCI clock
will be 33MHz, ISA Clock will be 8.25MHz when PCI clock divided by 4,
and 11MHz when PCI clock divided by 3.
System BIOS Cacheable
This category allows the user to set whether the system BIOS F000~FFFF
areas are cacheable or non-cacheable.
