I have an ASUS P5K-E motherboard which includes 5 drives; (2) - 500MB Raid 1, 400MB, (2) - 74MB Raid 1 and XP OS. One of the 74MB drives which includes Microsoft XP has died. Originally the software showed the drive as dead and offered me an option to rebuild which I did. When the CPU was powered down and then powered up the system cannot find the OS. I was told to hit to bring up the ROM version of ISMM when the machine is powering up to remove the good drive from the raid array so the system can boot from this drive. For whatever reason the system does not respond to to invoke ISMM. I tried removing the bad drive and eventually the good drive and still I cannot get ISMM to load.
