Also had this with an AWARD flashtool, wasnt really nice while flashing the mobo. Makes the bootdisk urgently useless for me or does this message only show with freedos????

Yes, I have the same problem. I use a Medion Laptop + Toshiba HDD + UBCD 3.3.

I have the message "MCB corrupted" everytime I launch freedos. Other boot disks (linux) boot fine. So I cannot run any soft working with freedos!

Fantastic!

Hi

I have an IBM R31 ThinkPad and I also cannot use anything that
starts off in FreeDos. (PANIC MCB Chain corrupted).
CD looks like it might be helpful, but..........

Just to confirm, did you guys try one of the other memory options during startup (EMM386 etc.)? That might help.

How do you do this thing with EMM386 ??
I tried it with the Insert-Taste, but I don't see this option "EMM386".

Thanks

I was referring to FreeDOS. When you launch FreeDOS, the first screen gives you a bunch of memory options to choose from.

Why is that? (I've been using UBCD v2.4 for years with no problems -- and no "memory options" to choose from.)

Now that I am trying to get v4.1.1 up and working I am finding that all of the apps that use "dosubcd.igz" don't work. I have tried a number of these "memory options". Almost all fail - with different errors.

I've searched this forum and found some stuff relating to an updated copy of FreeDOS -- but that doesn't seem to work either.

What is the solution to this?

Is there a post on how to use a DOS v6.2 or Win98 boot floppy to start the apps instead of FreeDOS?

Try UBCD50b12 and see if the problem persists.

OK -- I'm downloading it now. Will be able to burn a CD and test sometime on Monday.

However, how about explaining what's going on with the "memory options"?

Why do they appear?

And... is there a post on how to create a DOS 6.20 or Win98 boot floppy so we could use that instead of FreeDOS?

I burned v5 iso to CD -- NO JOY!! (same "memory management" screen appears).
