I've an circa 2001'ish PC that won't boot from usb. But I found http://www.plop.at/en/bootmanager.html does! I'm using grub and I just added an entry for Plop, which then gives me an option to boot from USB.
Thanks for the tip. I tested PLOP thoroughly and it didn't quite work for me. It appears that the PLOP drivers aren't completely compatible with the circa-1997 USB UHCI on the P II Micron laptop in question. Even though I set the PLOP option for USB 1.1 mode, it booted TC OK, got part way through the boot process and stalled. Same behavior with SliTaz Linux. I tested booting the USB sticks on my desktop before and after my laptop tests. The sticks booted perfectly. I also noted that a cold boot on the laptop helped a bit; warm boots were much more problematical. The laptop runs TC and SliTaz off of HD perfectly (albeit slowly...)
While I wasn't as thorough in testing TC PXE boots previously, it appears that my PCI wired ethernet adapter may not be supported by the PXE floppy boot disks. Works fine when running TC or SliTaz from HD.
I saw a cheap external drive case for 2.5" IDE HDs (just $6 S/H) and bought it. I'm going to pull the laptop HD, attach it to my desktop and do a better job of partitioning, installing DOS tools, TC, and SliTaz. Great little spare computer, running the right software. Just a
real pain to install to because of the primitive BIOS (no USB CD or flash boot), broken CDR, primitive USB UHCI, PCI ethernet, etc.
BTW, I ran across a post about using
BG-Rescue Linux (
installable from 2 floppies) to copy the Arch Linux kernel and then do an FTP Arch install. I haven't tried it, but the process is well documented and user comments were favorable. The process would be adaptable to TC and other Linuxes.
