I am replacing a failed (X5DA8) board with X7DA8, this one is in essentially the same configuration and hardware with the exception of the graphic card. Trying to load the "RAID" driver during installation of Windows XP with SP 1 or Sp 2. Continually getting this error: "File txtsetup.oem caused an unexpected error (1026) at line 1747 in d:\xpsprtm\base\boot\setup\oemdisk.c"
Check and make sure you have all the drivers on the floppy disk and use the standard floppy driver for Windows XP to specify. https://www.supermicro.com/wdl/CDR-LPZCR2_1.03_for_AOC-LPZCR2_AOC-LPZCR3/Driver/Windows/Build8389/SATA_SCSI/ If yes, then you might need to try different floppy diskette and make sure it is in full format.
