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

ISOLINUX 1.75 2002-06-14 isolinux failed to get sector size, assuming
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

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?
