Chapter 2 BIOS Setup AGP Aperture Size (MB) Select the size of Accelerated Graphics Port(AGP) aperture. The aperture is a portion of the PCI memory address range dedicated for graphics memory address space. Host cycles that hit the aperture range are forwarded to the AGP without any translation. The Choice : 4M, 8M, 16M, 32M, 64M, 128M, 256M. SDRAM RAS-to-CAS Delay This field lets you insert a timing delay between the CAS and RAS strobe signals, used when DRAM is written to, read form, or refreshed. Fast gives faster performance; and Slow gives more stable performance. This field applies only when synchronous DRAM is installed in the system. SDRAM RAS Precharge Time If an insufficient number of cycles is allowed for the RAS accumulate its charge before DRAM refresh, the refresh may be incomplete and the DRAM may fail to retain data. Fast gives faster performance; and Slow gives more stable performance. This field applies only when synchronous DRAM is installed in the system. SDRAM CAS latency Time When synchronous DRAM is installed, the number of clock cycles of CAS latency depends on the DRAM timing. Do not restet this field form the default value specified by the system designer. CPU Host Clock The setting are Hardware, 66MHz, 68MHz, 75MHz. Hardware (default) 2-19
