CHAINing to a USB Thumb Drive

I was doing a laptop repair job today and needed to boot from a USB
thumb drive, in order to free up the CD/DVD burner. Fortunately, the
laptop to be repaired permitted one to boot from a USB thumb drive.
However, there are still PCs out there that can't boot from a thumb
drive (I have two), so I was wondering if it's pos to use the CHAIN
module to boot from a thumb drive ? I looked at the source for the
module, but no joy there.

If CHAIN can't be used, does anyone on the list have a suggestion for
enhancing my SYSLINUX project w/ a tiny Linux distro, which could be
used as a simple USB thumb drive bootstrap ? TIA....Jet

Bootloaders like syslinux load kernels and start (boot) them.

They need to be loaded and started them self,
it is the software in ROM who does so.

When the computer lacks USB thumb drive boot software,
then are "second stage" bootloaders helpless

Look for "first stage" bootloaders like coreboot and gPXE.

Perhaps the first question would be: where are you chaining *from*?

COREBOOT seems/looks promising ! Thanx for the heads-up. Further
reading will be needed to determine if a *generic* CD-based, 1st-stage
boot (via COREBOOT) is pos, but this is at least new and purposeful info
(to me.)

Thanx again....Jet

Coreboot is the new name for the LinuxBIOS project. It's quite
interesting, as it's an opensource BIOS replacement with
additional/different abilities compared to traditional BIOS.
I have no idea if any project has a complete isolated software El-Torito
stack to allow CD booting. Smart Boot Manager has one, but it's
integrated into the program itself. GRUB might be able to do CD booting
as well. There exists a COM32 port (done by Jeremy Davis) of Smart Boot
Manager, and it's included in one of the bootdisks made for an old
version of the Freedos project:
