Memory Hole

This option specifies the location of an area of memory that cannot be addressed on the ISA bus. The settings are Disabled, 512KB-64KB, or 15MB- 16MB.

P2C/C2P Concurrency

By enabling this function the PCI/AGP Master to CPU Cycle can be concur- rent if the Host CPU is performing R/W access to the PCI or slave devices.

Fast Read Write turn-around

If Enabled, it reduces the turn around time for a memory read is followed by a memory write consecutively.

CPU IOQ Size

This setting controls the In Order Que of the CPU with the chipset, setting it to higher levels yields higher performace, although system may become unstable. Default is set to 1 Level.

System BIOS Cacheable

If Enabled, results in better system performance by permitting caching of the system BIOS ROM at F0000h-FFFFFh. Any program which tries to write to this memory area, however, may cause a system error.
