Syslinux - Jan 2003 - iso 2.00 isolinux: Checksum error, sorry...

Hi,

I tried to install redhat 8.0 on a laptop and ran into the following
problem.

ISOLINUX 1.75 2002-06-14 isolinux failed to get sector size, assuming
0800
isolinux: Image checksum error, sorry...

At that point, I followed the advice on the isolinux webpage, and
reburned a CD using isolinux 2.00 with debug.  The error message was:

ISOLINUX 2.00 2002-10-25 Copyright (C) 1994-2002 H. Peter Anvin
isolinux: Starting up, DL = 90
isolinux: Loaded spec packet OK, drive = 90
isolinux: Loading main image from LBA = 0000247B
isolinux: Sectors to load = 0004
isolinux: Loaded boot image, verifying
isolinux: Image checksum error, sorry...

I created the image following the redhat 8.0 release notes:
--
If you want to make your own CD to boot the installation program, copy
the isolinux directory from the first CD into a temporary directory (cp
-r /path/to/tree/isolinux/ /path/to/cdimage) and then run the following
command:

mkisofs -o /path/to/file.iso -b isolinux/isolinux.bin -c
isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -R -J
-V -T /path/to/cdimage
--

At that point, I burned another cd using syslinux-1.60 debug, which had
the same problems.  All the burned CDs work on other machines CDROM
drives.  The machine in question is a laptop, HP Pavillion zt1000.  It
has a DVD/CDRW drive, a TOSHIBA DVD-ROM SD-R2102.

Has anyone else seen this problem? Is there a workaround? 

Thanks,
Greg

This means that your BIOS loaded the wrong sectors, or the wrong number 
of sectors. but reported success.  It's probably close to impossible to 
work around, at least unless it's a trivial problem (such as the BIOS 
using 512-byte sectors instead of 2048-byte sectors as it's supposed to...)
