I updated the Bios for my Trigem IM845GL motherboard. During the system booted up sequence it displayed the new Bios software screen then just before booting up the operating system (windows xp) it said: 'A disk read error occurred, please press ctrl+alt+del to restart'. I think I might have installed the wrong Bios drivers?? I have checked the bios to ensure that the hard-disk is the main bootup drive and it is. I have reset the bios by moving the jumper blocks leaving them in the 2-3 position for 30 seconds replacing them to 1-2 position. But it did not clear the bios. Since the computer came with a specialised company software on two disks by setting up the bootup to be the cd-rom drive and putting in the disk it only has the option of deleting the data on the hard-disk and re-installing all the standard software. I don’t want to loose the data so this isn't a option. Can anyone please help as this is really doing my head in!!!!
