I have work arounds for all of these problems. Laptops are the most difficult however, since upgrades are limited to pcmcia, as well as type I and II support. So far I’ve had success with all of my laptop investments; my very old Compaq Armada, NEC Ready 220T, and my NEC Versa Sxi. I’ll be picking up a new Gateway 4530gz later in the week.
If there is enough support, I’ll seriously consider writing something up.
The idea is to be able to run DOS fully, no problems, on any modern machine.
