This should upgrade your BIOS for larger HDD support. Unzip to get an exe file. Run this to get the program and data files. Save all files to a bootable floppy. Boot your PC from the floppy. Run the Awdflash program. Enter the new BIOS name (AI5TV8.bin) including the BIN extension. When asked to save your old BIOS say yes - just in case...!. When this has saved, say yes to program your BIOS. Ignore the error about program file number not matching. Worked ok for me - recognised my 13GB HDD.
