Video RAM Cacheable
Selecting Enabled, you receive a warning message if a program
attempts to write to the boot sector or the partition table of the
hard disk drive. You should then run an anti-virus program.
Keep in mind that this feature protects only the boot sector, not
the entire hard drive.
8-16 Bit I/O Recovery Time
The I/O recovery mechanism adds bus clock cycles between PCI
originated I/O cycles to the ISA bus. This delay takes place
because the PCI bus is much faster than the ISA bus.
These two fields let you add recovery time for 16-bit and 8-bit
I/O.
Passive Release
When enabled, CPU to PCI bus accesses are allowed during
passive release. Otherwise, the arbiter only accepts another PCI
master access to local DRAM.
Delayed Transaction
The chipset has an embedded 32-bit posted write buffer to
support delay transactions cycles. Select enabled to support
compliance with PCI specifications version 2.1.
AGP Aperature Size (MB)
Select the size of the Accelerated Graphics Port (AGP)
aperature. The aperature is a portion of the PCI memory address
range dedicated for graphics memory address space. Host cycles
that have the aperature range are forwarded to the AGP without
any translation.
