I have 4 x 1GB Samsung modules in your X5DA8 board, but when boot into Windows 2000 that only report 3.7GB, why?
The Pheonix, AMI, Award BIOS use 4GB memory location to map add-on devicesâ?? Option-Rom, so if you have multiple add-on cards like onboard SCSI, Lan, or Raid controllers, then the BIOS will take 128~256MB main memory space for those add-on cards Option-ROM.
