DRAM RAS# Precharge | This item controls the number of cycles for Row | 2T, 3T, 4T |
| Address Strobe (RAS) to be allowed to precharge. |
|
| If insufficient time is allowed for the RAS to |
|
| accumulate its charge before DRAM refresh, |
|
| refresh may be incomplete and DRAM may fail to |
|
| retain data. This item applies only when |
|
| synchronous DRAM is installed in the system. |
|

|
System BIOS Cacheable | Selecting Enabled allows caching of the system | Enabled |
| BIOS ROM at | Disabled |
| system performance. However, if any program |
|
| writes to this memory area, a system error may |
|
| result. |
|
|
|
|
Video BIOS Cacheable | Selecting Enabled allows caching of the video BIOS | Disabled |
| ROM at C0000h to C7FFFh, resulting in better | Enabled |
| video performance. However, if any program writes |
|
| to this memory area, a system error may result. |
|
|
|
|
Memory Hole at | In order to improve performance, certain space in | Disabled |
| memory can be reserved for ISA peripherals. This | Enabled |
| memory must be mapped into the memory space |
|
| below 16MB. When this area is reserved, it cannot |
|
| be cached. |
|
|
|
|
Delay Prior to Thermal | When the CPU temperature reaches a factory | 4 Min, 8Min, 16 Min, 32 Min |
| preset level, a thermal monitoring mechanism will |
|
| be enabled following the appropriate timing delay |
|
| specified in this field. With the thermal monitoring |
|
| enabled, clock modulation controlled by the |
|
| processor’s internal thermal sensor is also |
|
| activated to keep the processor within allowable |
|
| temperature limit. |
|
|
|
|
AGP Aperture Size (MB) | This setting controls just how much system RAM | 4, 8, 16, 32, 64, 128 and 256 |
| can be allocated to AGP for video purposes. The |
|
| aperture is a portion of the PCI memory address |
|
| range dedicated to graphics memory address |
|
| space. Host cycles that hit the aperture range are |
|
| forwarded to the AGP without any translation. |
|
|
|
|
Init Display First | This item specifies which VGA card is your primary | PCI Slot |
| graphics adapter. | Onboard/AGP |
|
|
|
This setting determines whether the system RAM | Enabled | |
| can be allocated to | Disabled |
| video purposes. When setting to Enabled, up to |
|
| 128MB system RAM will be allocated to |
|
| video controller. |
|
|
|
|
Frame Buffer is the video memory that stores data | 1M, 8M, 16M | |
| for video display (frame). This field is used to |
|
| determine the memory size for Frame Buffer. |
|
| Larger frame buffer size increases video |
|
| performance. |
|
|
|
|
Boot Display | Use this field to select the type of device you want | Auto, CRT, TV, EFP |
| to use as the display(s) of the system. |
