I have a very old Cyrix 166 powered PC (Award Modular _AI5TH2_ board) on which I want to format the HDD and start again. Unfortunately the machine seems to have other ideas as it wont allow me to boot off the FDD or CDROM drive. I have changed BIOS boot sequence setup to check FDD and CDROM first but to no avail. Despite there being bootable disks inserted the machine reads them for a couple of seconds and then switches back to the HDD to continue to boot.
Any ideas whats going on and how I can remedy it?
