I am attempting to upgrade an older 66 MHz bus motherboard with 128MB PC66 SDRAM DIMM. NVRAM initialization during BIOS screen only recognizes 32MB. Book says board is upgradable to 128MB DIMM with SDRAM. Jumpers seem to be set right (3.3V). CMOSseems to be set right also. No option for bus speed settings in CMOS. Got any ideas? Send email to eansor@concentric.net Thanks!
