AGP Always Compensate:
Two options are available: Disabled
)
Enabled. The default setting is Enabled . When set to Enabled,
dynamic compensation will be performed by the AGP .
SDRAM ECC Setting:
Four options are available: Disabled

Scrub. The default
setting is Disabled . When your DDR SDRAM module supports the ECC function, set this item to
Scrub. You can also set to others items except Disabled. The detailed functions are mentioned
below:
Disabled: ECC disabled, no error detection or correction is performed.
Check Only: EC_HiPerf mode enabled, Error checking and status reporting is enabled. Data destined
for the PCI/APC/AGP and memory (RMR) is
not corrected.
Correct Errors: EC_HiPerf mode enabled, Error checking and status reporting is enabled. Data destined
for the PCI/APC/AGP and memory (RMR) is corrected.
Scrub: ECC_Scrub mode enabled. Error checking and status reporting is enabled. Data destined
for the PCI/APC/AGP and memory (RMR) is corrected. The memory contents are
corrected (scrubbed) after all reads with errors.
Super Bypass Mode:
Two options are available: Disabled or Enabled. The default setting is Enabled . When set to Enabled,
IGD4 internally bypasses certain memory to CPU pipe stages for optimal performance. This item may
only be set to Enabled if both of the following are true:
1. System is single processor or system is dual processor and only CPU0 (1st processor) is present.
2. CPU clock divisor is 4:1 or greater.

Super Bypass Wait State:
Two options are available: 0 Cycle and 1 Cycle. The default setting is 0 Cycle . This bit forces a wait state
on all Super Bypess Reads. If you choose “1”, which means you add wait state on Super Bypass reads.
