I have the following advanced settings in my AwardBIOS:

Read around write [Disabled/Enabled]
CPU-DRAM Back-Back Transaction [Disabled/Enabled]
Delayed Transaction [Disabled/Enabled]
PCI to DRAM Prefetch [Disabled/Enabled]
Byte Merge [Disabled/Enabled]
DRAM Read Latch Delay [0.0ns/0.5ns/1.0ns/1.5ns]
Graphics Aperture Size [4MB/8MB/.../256MB]
Video Memory Cache Mode [UC/USWC]

What do each setting do, and how do I optimise my settings?

FWIW, the specs are: ASUS CUV4X, PIII 1GHz, 384MB PC-133 SDRAM (2 x 128MB single sided, 1 x 128MB double sided DIMM), GeCube RADEON 7000 64MB AGP 4x, running WinXP Pro SP2

if you do not want to overclock, i should leave them as set by the autodetect functions of the board.
