Freedos Hangs at InitDisk

I have tried this with 2 different USB sticks (Cruzer 1Gb and Maxell 2Gb) and 3 PCs including an IBM desktop, all will boot and display the Blue menu screen with various tools/utils listed, but selecting the ones that use Freedos produces a screen that appears to setup some kind of virtual disc and then a license message
The line after that reads

Code: Select all

- InitDisk
Invalid Opcode at 00D7 0624 0212 4080 0002 0000 0000 0000 0000 0000 0000 0000 0000
The only thing you can do then is press Ctrl+Alt+Del or switch off.

Any ideas what is going on?

This problem was identified a while back (it has to do with the extended memory manager). Update the FreeDOS image...
viewtopic.php?t=1422

This should fix the problem.

Thanks

I have the download but I am not sure what I am doing to edit the iso image?

Do I need a program to do this?

There exist a number of ways you can choose to approach this. If you have an archiver such as 7zip or WinRAR, you can unpack the entire contents of the UBCD ISO to your harddisk. Suppose we unpack it to C:\ubcd.

Once unpacked, browse to the following directory...

Code: Select all

C:\test\ubcd\images
There should be a file named "dosubcd.igz"....replace this with the newer version provided in the link I provided above (you'll need to unzip the archive).

Once complete, browse to...

Code: Select all

C:\test\ubcd\tools\ubcd2iso
There's a batch file named "ubcd2iso.cmd". In order to re-master the ISO, you'll need to open a command prompt and browse to the file location and type

Code: Select all

UBCD2ISO c:\test c:\ubcd50b4.iso
Done. Alternatively, you can use a program such as MagicISO to open the ISO and "drag-and-drop" the newer file into the image.

I have rebuilt the image and reformated the USB drive and run fixubcd2.bat again to copy the files from the image and make it bootable. But it still hangs at the --Initdisk line

It seems as though Freedos just stops there, it appears to be waiting on some item.
