Important:  Make sure that your Bios fully supports the el-torito cd format. 
            Incompatible bios versions include:
            - Phoenix Award Bios v6.00PG
            - Insyde BIOS with Intel Macs

For both M32 and M64:

Create a bootable MenuetOS CD from ISO header file and Menuet 1.4MB image.

1) Download and unzip and Menuet image.

2) Combine the header with Menuet image

   Dos:  copy /b isohdr + Mxx-xxx.img mboot.iso
   Unix: cat isohdr Mxx-xxx.img > mboot.iso

3) Burn mboot.iso to CD and boot

   CD burning application should recognize the used 'el-torito cd' format.

Note that the CD image is for booting only and does not include a ISO9660 filesystem.
