After 5 years of use my MSI K8N Neo4 Platinum (7125) mother board died. The mother board that died used an 80GB hard drive for booting with a 200GB EIDE hard drive for data. The mother board supports 2 types of RAID and neither was in use. The BIOS was AWARD v1.1. I purchased a used replacement mother board (same as the one that died, MSI K8N Neo4 Platinum 7125) and after installing the mother board I could not get the system to boot. I kept getting a boot disk failure. I checked the BIOS to ensure the hard drives were recognized and the the boot sequence for the hard drives was correct. The hard drives were recognized and the sequence looked to the SATA hard drive first. Then I realized the BIOS on the replacement mother board was at a different level Award v1.B. I replaced the BIOS chip in the replacement board with the v1.1 BIOS chip from the board that died and the system booted fine. I checked to see if both drives were recognized by the v1.1 BIOS and the EIDE hard drive was NOT recognized even though the operating system (XP Media Center)did recognize it and that is why the system booted ok. I then flashed the v1.B BIOS chip to v1.D (the last supported for this mother board)to see if the problem had been fixed and when I booted the system again I still received the boot disk failure error. Upon checking the contents of the BIOS, both hard drives were recognized and so I changed the hard boot sequence to look at the SATA drive first, rebooted the system with the same failure. It appears that the hard boot sequence in the BIOS does not work. As long as the EIDE drive was recognized by the BIOS it goes to that drive first and only. I turned off the EIDE drive in the BIOS (v1.D) to make it look like the V1.1 BIOS and rebooted. The system came up correctly and the operating system found the EIDE hard drive and everything appears to work.

As the BIOS for this mother board will not be updated as the board is not manufactured anymore I felt this issue should be documented for us older mother board users (if it has not already).

Well...a lot of boards have no native SATA support...but Windows can be installed, as long as the SATA drivers are installed during the Windows install process.

Even if the board has no native SATA suppport...any user can purchase a controller card and effectively bypass the motherboard limitations by booting from the controller card, after changing the system BIOS settings to boot from SCSI. The controller card is viewed as a SCSI device (often) in the system BIOS.
