I was using 5.1.1 with a bunch of custom BIOS update utilities that I integrated into UBCD without issue for quite some time.
Ever since 5.2 was released this doesn't appear to work any longer and I was hoping for some insight. I have even tried with 5.2.4 (released today) with the same problem.
What happens is that the image just stops and freezes the computer. Here is a screenshot of where it freezes:

Here is how I have it setup and working in 5.1.1:
LABEL -
MENU LABEL SOME BIOS
TEXT HELP
VERSION
ENDTEXT
LINUX /boot/syslinux/memdisk
INITRD /ubcd/biosupdates/laptops/SOMEBIOS.ima
APPEND raw
I noticed things have changed around with 5.2, so I tried what appears to be the way to use memdisk now:
LABEL -
MENU LABEL SOME BIOS
TEXT HELP
VERSION
ENDTEXT
COM32 linux.c32 memdisk
INITRD /ubcd/biosupdates/laptops/SOMEBIOS.ima
APPEND raw
(I have also tried "APPEND floppy raw" as well as "APPEND floppy raw c=XX h=X s=XX"
Here is a copy of one if the IMA's that I have created:

Its basically just a freedos floppy image which launch an HP BIOS update (ROMPAQ).
Doing it either way in 5.2 results in the problem with it freezing. Again there were no problems with 5.1.1 (and im pretty sure with other revisions of 5.1)
Could this be an issue with the included memdisk version or syslinux \ isolinux? It seems very strange that this worked fine in the older version but now does not.
Thanks for the help and assistance.
