3.5.7 System BIOS Cacheable

Selecting Enabled allows caching of the system BIOS ROM at F0000h- FFFFFh, resulting in better system performance. However, if any pro- gram writes to this memory area, a system error may occur. The Choices: "Enabled", "Disabled".

3.5.8 Video Bios Cacheable

Selecting Enabled allows caching of the video BIOS, resulting in better system performance. However, if any program writes to this memory area, a system error may occur. The Choices: "Enabled", "Disabled".

3.5.9 Memory Hole At 15M-16M

Enabling this feature reserves 15 MB to 16 MB memory address space for ISA expansion cards that specifically require this setting. This makes memory from 15 MB and up unavailable to the system. Expansion cards can only access memory up to 16 MB. The default setting is “Disabled.”

3.5.10 Delay Prior to Thermal

Select the period if user wants to lower the CPU speed when CPU tem- perature is too high. The choice: "4 Min", "8 Min", "16 Min" and "32 Min".

3.5.11 AGP Aperture Size (MB)

Select the size of Accelerated Graphics Port (AGP) aperture. The aper- ture is a portion of the PCI memory address range dedicated for graphics memory address space. Host cycles that hit the aperture range are for- warded to the AGP without any translation. The Choice : "4", "8", "16", "32", "64", "128", and "256".

3.5.12 Init Display First

Choose the first display interface to initiate while booting. The choice is "PCI Slot" or "Onboard".

3.5.13 On-Chip VGA

User can disable onboard VGA controller by selecting "Disabled"

3.5.14 On-Chip Frame Buffer Size

User can select frame buffer size. Option is :"1MB", "8MB" and "16MB".
