this is the final FINALrelease of UBCD V5.0, warts and all. This is slightly different from the version posted here. Here are the changes:

- Updated UBCD FreeDOS to V1.37. \ubcd\custom\custom.ini is processed together with \ubcd\dosapps\ubcd.ini. Also added "-m" to "mdiskchk.com -b" else the ubcdcmd= parameter passed to the ISO is not detected.
- Added missing rm.exe and cat.exe to \ubcd\tools\win32\unxutils.
- Updated HDClone to V3.9.1.
- Updated SeaTools for DOS to V2.20.
- Updated AVIRA AntiVir Rescue System to V3.6.9-20100512182845.

The first change lets you isolate custom FreeDOS apps to "c:\ubcd-extracted\ubcd\custom", instead of having to modify "c:\ubcd-extracted\ubcd\dosapps".
