TODO

TODO: glue two credit cards together, and dremel a precise hole in it with 2 or 3 "friction tabs" that can hold the 2GB thumb in the middle (so I can keep the thing in my wallet)

Boot Configuration

DVD
- top-level: grub4dos's no-emulation loader
  - DOS — two-stage, using eltorito.sys to load the second stage
  - Linux — easy with grub
2.5" HDD
- top-level: MS-DOS, config.sys menu
  - DOS — already there
  - floppies — config.sys → grub.exe → floppy.img via grub4dos's version of MEMDISK
  - Linux — config.sys → grub.exe

DOS apps

Most DOS apps are small (small enough to keep on a boot floppy), so it's easy to keep the same set of programs on all of your boot media. These are mine:

Ghost (Norton) — versions 8 and 11, maybe other versions.
Grub4Dos — while optimally it should be installed in config.sys, it can often be run manually after bootup as well. IMHO, it's the most feature-full of the GRUB v1 variants.
PC Check (Eurosoft) — good for laptop manufacturing testing
