[syslinux] Isolinux bug: CD bootsector support broken

[Michael_E_Brown at Dell.com]

HPA,
	I believe that support to boot windows CD bootsectors was broken
in 3.05. I have tested 2.13, 3.00, 3.02, 3.05, 3.06, 3.08, 3.11, and
3.20pre6. All versions >= 3.05 are broken. All versions <= 3.02 work
fine with the same config. The error message I get is:

================================================================
IOSLINUX 3.20 3.20-pre6   Copyright (C) 1994-2005 H. Peter Anvin
boot:
.

ISOLINUX 3.20 3.20-pre6 isolinux: Image checksum error, sorry...

Boot failed: press a key to retry...
================================================================

	I looked in the various testing/ dirs to try to locate a -preX
for 3.05 to narrow down the exact version where it broke, but I was
unable to locate -preX releases for 3.05. I read the isolinux.doc and
NEWS to try to determine if the options have changed, but did not see
anything relevant. I read I tried to search the mailing list for similar
problems, but did not see anything similar.

	The CD is laid out like below. I have tried both longhorn and
w2003 CD bootsectors. The results are the same.

	I would be willing to try any betas to fix this, but it should
be easily reproducable. You can download the wxp10.zip from the BartPE
website to get the boot sector.

Thanks,
Michael Brown
