[syslinux] Dell OptiPlex GX620 can longer boot from CD with syslinux-5.X

[Patrick Verner]

Sorry for the delay, we were too busy drinking and playing with explosives
yesterday. :)

Here are some tests. We did one on a similar machine and it worked.
We deleted the configuration file, obviously.

# Dell OptiPlex GX620
ISOLINUX 5.11 5.11-pre7
isolinux: Starting up, DL = 82
isolinux: Loaded spec packet OK, drive = 82
isolinux: Main image LBA = 00000115
isolinux: Image checksum error, sorry...

# Dell OptiPlex GX620
ISOLINUX 4.06 0x513e88f5
isolinux: Starting up, DL = 82
isolinux: Loaded spec packet OK, drive = 82
isolinux: Main image LBA = 0000011D
isolinux: Main image read, jumping to main code...
ERROR: No configuration file found
No DEFAULT or UI configuration directive found!
boot:

# Dell OptiPlex 9010
ISOLINUX 5.11 5.11-pre7
isolinux: Starting up, DL = EF
isolinux: Loaded spec packet OK, drive = EF
isolinux: Main image LBA = 00000115
isolinux: Main image read, jumping to main code...
WARNING: No configuration file found

Hope this helps. Lets us know if you need anything.
