Solved Boot With An MS-DOS Drive

  • 0

Hi There,
I had an old laptop with a “valuable” MS-DOS system installed on it.
Years back I cloned this and was able to boot it in a 32bit PC without problem.
I now have a 64Bit machine and when I try to boot to the drive I get the usual “Starting MS-DOS” then the usual “HIMEN is testing extended memory…..done” but then it hangs there without booting up.
Put the disk back in a 32bit machine and it works great.
I’m sure I have had this working before on my 64 bit machine and I think I did something, who knows. I recall some time ago going into the BIOS to check some performance settings but I don’t think I did much really.
The BIOS is American Megatrends Inc 0502, 31.8.11. SMBIOS version 2.6,
Any help would be much appreciated.
Regards
Paul

      Make an image of your DOS hard disk using WinImage Professional (shareware with a limited free trial) then run DOS inside a virtual machine booting from the vhd image created. MS Virtual PC or VirtualBox are both free and very effective in running under the most up to date operating systems and 64 bit hardware.
