Intel CB60-ZX, CB60-BX manual Video RAM Cacheable, Memory Hole At 15M-16M, PCI 2.1 Compliance

Award BIOS Setup Utility

Video RAM Cacheable

When enabled, it allows the video RAM to be cacheable thus providing better video performance. If your graphics card does not support this function, leave this field in its default setting - Disabled.

8 Bit I/O Recovery Time and 16 Bit I/O Recovery Time

The recovery time is the length of time, measured in SYSCLK, which the system will delay after the completion of an input/output request. This delay takes place because the CPU is operating so much faster than the input/output bus that the CPU must be delayed to allow for the completion of the I/O. This item allows you to determine the recovery time allowed for 8-bit I/O or 16-bit I/O.

Memory Hole At 15M-16M

In order to improve system performance, certain space in memory can be reserved for ISA cards. This memory must be mapped into the memory space below 16MB. When enabled, the CPU assumes the 15- 16MB memory range is allocated to the hidden ISA address range instead of the actual system DRAM.When disabled, the CPU assumes the 15-16MB address range actually contains DRAM memory. If more than 16MB of system memory is installed, this option must be disabled to provide contiguous system memory.

PCI 2.1 Compliance

By default, this field is Disabled. However, if you encounter problems with your PCI card, try setting this field to Enabled. It may be that your card is PCI 2.1 compliant.

AGP Aperture Size (MB)

This field is relevant to the memory-mapped graphics data of the AGP card installed in your system. Leave this in its default setting, which is 64MB.

CPU Clock Frequency

If you are using a 66MHz FSB processor, the options are Default, 66MHz, 75MHz and 83MHz. If you are using a 100MHz FSB processor, the options are Default, 83MHz, 100MHz, 103MHz, 105MHz, 110MHz, 112MHz, 115MHz, 120MHz and 124MHz.
