AMI BIOS Utility
3-13
Memory Hole
This option lets you assign the system memory area to avoid memory conflicts.
The settings are 512~640K, 15~16M and Disabled.
8-bit I/O Recovery Time (Sysclk)
This parameter allows you to set the response time of the 8-bit I/O devices
connected to your system. The settings range from 1-7 SYSCLK and
Disabled.
16-bit I/O Recovery Time (Sysclk)
This parameter allows you to set the response time of the 16-bit I/O devices
connected to your system. The settings range from 1-4 SYSCLK and
Disabled.
DRAM Timing
The selections for this parameter are 60 ns, 70 ns, and Manual. If
you select either 60 ns or 70 ns, the DRAM Timing subparameters
become nonconfigurable since BIOS automatically sets the values. Select
Manual if you want to specify your own parameter settings.
DRAM REFRESH RATE
This option lets you specify the DRAM refresh rate. The selections are 50
MHz, 60 MHz, 66 MHz, and Reserved.
ISA CLOCK DIVISOR
This option specifies the system bus clock divisor. The selections are
PCICLK/4 and PCICLK/3.
TURBO READ LEAD OFF
When enabled, the BIOS skips the first input register in the DRAM when
reading data and therefore, speeds up the data read timings. Disable the option
to bypass the feature.
DRAM READ BURST TIMING
This parameter adjusts the read wait state between L2 and DRAM cache.
Everytime the CPU reads L2 cache miss, it reads four continuous memory
