I used the assistance of qemu to do this, it is probably the easiest and quickest way. Now that the stick is basically prepped, it is time to install FreeDOS on it.

If you don't have the install-mbr command, install the mbr package. Partitions, please see the fdisk manual page for additionalĪfter that I put a master boot record (MBR).

I did the following to put the partition table in place: Usually it is easiest to check the output from dmesg to see the device assigned. In the example below the stick was available as sdf. I reinitialised the USB stick, started by putting a new partition table in place. I used the small ISO, that is enough to make a bootable USB stick. Then I downloaded FreeDOS base CD from their website. So I searched for a bit and found an old 64MB USB memory stick to turn into a bootable device with DOS on it.

You can easily brick your system doing so.ĭownloading the required files from the Asus website indicated a DOS based executable for upgrading the BIOS. Could be there are mistakes, so take care when upgrading your own BIOS. A quick check in the BIOS revealed that the current version is 0804.Ī check on the support site for Asus show there are quite a few revisions available: Never checked to see if there was a new BIOS available for my netbook since I bought it.
