This is amazing. The stock 440gx bios sets the row page size for SDRAM I am using to 8kb. But the reported (from SPD) size is 4 KB (value of 0c in SPD reg #3). So linuxbios is right, the RPS is 4KB, and the stock BIOS is wrong. The stock BIOS is programming the north bridge incorrectly. I just love these BIOSes. ron
