Here's a list of programs which are not booting using the Ultimate Boot CD:
Not working:
BIOS-Menu:
!BIOS V3.20
BIOS V1.35.0
CMOSPWD V5.0
Keydisk
WipeCMOS V1.2
CPU Menu
Intel Processor Frequency ID V7.2 (P3 and below)
Here I stopped testing, it seems that each and every program which is launched from UBCD's DOS doesn't work.
Additionally, returning to the main menu results in:
/boot/syslinux/econfig.c32: not a COM32R image
