Hi guys,

i'm having issues with mdiskchk.com from the UBCD FreeDos Image.
This is resulting in a complete system freeze (not even Ctrl-Alt-Del possible) whenever mdiskchk.com is executed in the autoexec.bat

-> So a lot of programs on the UBCD are not usable for me!!

I'v tried to replace it with different versions (from Syslinux 3.80 and 3.86) and removed the "-m" attribute that has been added lately, but with no success.

btw. I'm NOT running UBCD in a virtual machine, it's my real pc! If necessary I could provide additional details about this machine...

Does it also freeze when you boot the "0 Boot Clean" submenu of the FreeDos image and execute:
Code:
mdiskchk

Can you post your exact model of motherboard and BIOS revision?

If you are running UBCD from USB, can you try the following and post the result after running the new entry "meminfo (E820 info)"(copy it down exactly or make a picture):
1. download Syslinux: http://www.kernel.org/pub/linux/utils/b ... x-3.86.zip
2. extract /com32/modules/meminfo.c32 from this archive and copy it to /boot/syslinux/ of your UBCD USB stick.
3. Add the folowing to /ubcd/custom/custom.cfg:
Code:
LABEL E820
MENU LABEL meminfo (E820 info)
COM32 /boot/syslinux/meminfo.c32

4. Boot UBCD ==> User-defined ==> meminfo (E820 info)
5. Take picture or write the info down.

ok, so executing mdiskchk in clean mode also results in a system freeze!

ok, so this has nothing to do with UBCD itself but how can I solve this problem?

replace mdiskchk with something else?
it hasn't been used before v5.0 right ?

I have reported the issue with mdiskchk.com upstream (Syslinux). I will let you know, when they want you to try a test version. I hope they can fix it.

Temporarily you can replace the following lines in autoexec.bat:
Code:
echo @echo off >%ramdrv%\bin\setargs.bat
mdiskchk.com -b -m >>%ramdrv%\bin\setargs.bat

with:
Code:
getargs.com >%ramdrv%\bin\setargs.bat

Can you try the following:

Extract the files:
http://ubcd.stopspazzing.com/downloads/ ... emdisk.zip

Place memdisk in /boot/syslinux/memdisk.
Place mdiskchk.com inside the FreeDOS image and run it as you did before ("0 Boot Clean").

Try this image (has update mdiskchk.com and eltorito.sys):
http://www.ultimatebootcd.com/misc/fdub ... z.20100621

Remove the .20100321 extension, when you save the file.
Place the file in /ubcd/images/.

Download MEMDISK from (click on blob):
http://git.zytor.com/?p=users/sha0/sysl ... =cdeaadbf3

Rename the file to memdisk and copy it to /boot/syslinux/

Now, boot from your USB stick, select FreeDOS:
Select the "0 Boot Clean" submenu of the FreeDos image and execute:
Code:
mdiskchk.com --no-sequential

Does it still freeze your PC or not?

If it doesn't freeze, try:
Code:
mdiskchk.com --no-sequential -m -b

And report the text you see (should be "set raw=1").

with:
Code:
mdiskchk.com --no-sequential

-> no freeze

with:
Code:
mdiskchk.com --no-sequential -m -b

-> no freeze either
output:

Code:
set raw=1
set initrd=/fdubcd3.img.gz
set BOOT_IMAGE=/boot/syslinux/memdisk


different path and filename for the image should be not a problem, does it?

No, it doesn't.
I only wanted to see if mdiskchk.com could grab the MEMDISK arguments without freezing. So the test succeeded :D .

@ Victor:
In AUTOEXEC.BAT:
Quote:
mdiskchk.com -b -m -n>>%ramdrv%\bin\setargs.bat

The newer eltorito.sys hangs in qemu (didn't try anything else atm).
I will let you know, when it is fixed.

although the changelog to V5.03 made me think that this issue has been fixed, it is not.

in autoexec.bat I can still see the line:
    mdiskchk.com -b -m>>%ramdrv%\bin\setargs.bat
instead of
    mdiskchk.com -b -m -n>>%ramdrv%\bin\setargs.bat

So my system is still freezing when using UBCD 5.03

No, this is not in the changelog. I have added it to my todo. Thanks!
