[syslinux] ISOLINUX problem booting with no Hard Disk

[Michael E Brown]

I am experiencing a problem booting a machine with ISOLINUX on a machine
that has no hard drive (CD-ROM only). I've tried two different machines, a
Dell Poweredge 2600 and a Dell Poweredge 1300, both exhibit identical
symptoms. When I boot the exact same cd on a system with a hard drive, the
boot is just fine.

I had been using ISOLINUX 1.66, but I just upgraded to 2.02 and I am 
having the exact same problem.

The messages from the debug version are:

ISOLINUX 2.02 2003-02-13  Copyright (C) 1994-2003 H. Peter Anvin

Ready.

After the "Ready." prompt, there are no more messages, the cursor stays on 
the next line under the "R", and the expected, "Uncompessing kernel..." 
message never appears. 

Anybody have any suggestions?
