Make sure that you partition and format the harddisk with the provided FreeDOS tools during install.Boot the virtual machine from the FreeDOS ISO and install the minimal version of FreeDOS on the virtual harddisk.Create a virtual machine with a harddisk of only 20 MB size, also attach the Full FreeDOS ISO as a CD-ROM.Extended editĪll you need is the Full FreeDOS ISO, a recent Linux LiveCD, an installed Linux and a Virtual Machine. Or try to search for 'boot ISO via PXE', 'boot DOS via PXE', etc. You can see a step-by-step tutorial here: Still with copying the files to a USB image and trying to boot from PXE it refuses to boot. To further complicate things the rom will only run when himem.exe and emm386.exe are running (they are started by selecting the second option on FreeDOS).ĮDIT2: I finally got the USB stick to work after adding the flat files to the stick and the COMMAND.COM from a custom freedos usb stick I found. I tried creating a larger image using these steps but have not had any success as each time I go to boot into the image it does not display the usual FreeDOS menu (it only prints out FreeDOS and gives no command prompt).ĮDIT: I was able to get the rom running off the FreeDOS image from here but of course when running the rom it says that the rom is corrupted because the entire rom is not actually on there and is only partially there due to there being only 1.44MB of space on the image. I found FreeDOS but they do not supply a bigger image than 1.44MB which is an issue because the firmware rom alone is 5MB in size. Should I be fine just dumping the flat files on my tftpboot server and then just adding in the proper bits for the pxemenu or is the process a bit more involved?

For some specifics the firmware updater is usually to be installed on a USB stick.

I was wondering if it was possible to make a PXE bootable image from a dos utility firmware.
