##USB sticks
USB sticks should be just as bootable as any other storage medium - as long as the BIOS supports it!
To that end, I've decided to collect a number of Master Boot Records (MBRs) for USB sticks that I own. Each *.mbr will simply be the 512-byte MBR at the beginning of each stick. If there's a *.asm with the same name, then it's a disassembly (courtesy of NASM's ndisasm.exe - edited with my comments).
For a very few cases, there may also be a Volume Boot Record (*.vbr).
It turns out that some USB sticks also come up as CD-ROMs, either in isolation or in addition to the drive. For those, I've added an *.iso file - no, not (necessarily) a complete image! I've only added sufficient (2 kiB) sectors that its peculiarities can be broken out. I'm assuming that the rest of the filesystem is 'normal'.
