How do I boot USB via boot floppy?
curaga:
It appears that the Plop Boot Manager should be able to do that - that is, chainload an usb stick with a linux bootloader.

It's freeware, no source, but the configuration utility is gplv2.
I could not get this to work; trying on two laptops that can't boot from usb, it hangs in the other and reboots the other.
If anyone wants to try it, here's a preconfigured file to dd into a floppy, that should autoboot an usb stick:

I've tried 1.4 and 2.0, I install directly from dos 6.11 ( yeah, oldschool)
None of these options work..
always getting the black screen..

Have you tried the post here a member showed me with ext3 formatted USB?
( [removed due to policy violation]/instau.html )
The trick is making grub think your installing to first harddrive, which works out great for me.
Note, my Emachines PC and my laptop cannot boot off usb.
My Emachines boots off USB using Plop bootmanager bootfloppy (plpbt.img) which comes as either a floppy or a cd. I can use either FAT32/syslinux USB or EXT3/Grub USB and both boot.
The laptop, however, will only boot the FAT32 syslinux usb using plpbt.img plop bootfloppy.
But, If I INSTALL Plop bootmanager to MBR, using (plpbtin.img), it will then boot both of them.
To put either bootmanager(plpbt.img) or bootmanager-install(plpbtin.img) on floppy
grab a clean, formatted floppy and dd'it
"dd if=/path-to-plpbt.img of=/dev/fd0 bs=1440k'
So, if the floppy image was on my Desktop it would be-
"dd if=/home/bz/Desktop/plpbt.img of=/dev/fd0 bs=1440k"
This really works and there are other bootmanagers too.
I have tc 1.4.3 for fat32/ext3 syslinux/grub.
basically, for ext3 usb follow the tutorial above and I have instructions inside too.
Please try it and tell me if any issues? ::)

An additional constraint is trying to deal with a first harddrive that is previously partitioned SOLELY with fat16 and fat32 partitions; NO free disk space at end!
How exactly can a grub boot floppy incorporate parted (or else boot and then recognize one of the first harddrive fat16/fat32 executable parted's) ??
Unsuccessful at this so far :'(

Perhaps there is a bootloader that supports reading off usb devices...? In that case you could just change the .cfg for that to read the initrd off the usb device

Maybe GAG is the answer: http://en.wikipedia.org/wiki/GAG_(boot_loader)
Good luck !
