Hey. I've built my comp for the first time but when I start it with a bootable cd I get an error.. Code: Starting PC DOS... (some information here that's not important) Device driver not found: ´MSC001`. No valid CDROM device drivers selected` I've checked in the bios and the motherboard can "see" the cdrom and that it's installed correctly. I've read somewhere that I need to check two files called autoexec.bat config.sys And I've tried editing them with the "edit" command but it only say that it doesn't know the edit command. The motherboard: Asus P5LD2-X/1333 i945GC 2DDR2-DIMM 3PCI 3PCIe SATA Audio LAN Socket775 ATX The CDROM: Samsung SH-D163B/BEBP 16X DVD-ROM/48X CD-ROM BLACK bulk SATA I'm new at this and would appreciate all the help I can get.
