Syslinux - Jan 2008 - isolinux regression? / problem? v3.50 and newer.

Greetings,

I have been using isolinux with Microsoft's cdimage.exe for my Utility / 
Preinstallation cds. I just upgraded from 3.36 to 3.55 and found it to 
be non functional. I didn't use the -debug version, it just hangs at the 
version banner. I went through several previous versions, and it appears 
that 3.50-pre23 is the last working version. I didn't see anything 
between that and 3.50-release?! 3.55 was tested as a burned cd on 
several machines, all version testing after was with vmware and iso image.

Of course this could be some change that I didn't see listed, and I need 
to modify my procedure for. I am using cdimage as I had issues with 
mkisofs previously. I don't recall what / why. I can try mkisofs again 
later.

I am calling cdimage like so:
cdimage.exe -Lmycd -t08/23/2001,09:00:00 -b\cd\isolinux\isolinux.bin -h 
-n -o -m C:\cd C:\test.iso
cdimage is v 2.47
isolinux.bin and isolinux.cfg is in \isolinux. I do not have a \boot

-t sets the time stamp for all files/dirs
-h includes hidded files/dirs
-n allows long filenames
-o optimizes the image by encoding duplicate files only once

I will investigate playing with these options to see if I can get newer 
versions working.

The non-working output (typed):
ISOLINUX 3.50 2007-06-09 Copyright (C) 1994-2007 H. Peter Anvin
isolinux: starting up DL=9F
isolinux: Loaded spec packet OK, drive = 9F
isolinux: No boot info table, assuming single session disk...
isolinux: Spec packet missing LBA information, trying to wing it...
isolinux: Loading main image from LBA = 0000011C
isolinux: Sectors to load = D5B7

and hangs there indefinitely.

The working 3.50-pre23 output (typed):
ISOLINUX 3.50 3.50-pre23 Copyright (c) 1994-2007 H. Peter Anvin
isolinux: Starting up, DL =9F

isolinux: Main image read, jumping to main code...
isolinux: Root directory at LBA = 0000001C
isolinux: isolinux directory at LBA = 00000030
isolinux: About to load config file...
isolinux: Configuration file opened...
boot:

Any ideas? Currently my test image is quite large, I will try and create 
a test image that is smaller tomorrow.

mkisofs might help, since the lack of boot info table seems to be biting 
you.

This means that neither the boot info table nor the spec packet has the 
appropriate information.

Clearly something is still wrong in the "winging it" code.  I
don't get
around to testing it much.
