I've been buying some older computers off Ebay to develop code for embedded systems running real-mode DOS. The embedded controller boots and runs off of USB devices, comes with FreeDOS and will run DOS 7.1.
The Panasonic CF-51 toughbooks provide the same feature, and have IDE drives. SO- I can boot into the same OS as the embedded controllers, write and test code, use a regular Copy to load new software onto a CF card or SD card to run on the embedded controller. Saves a step up dual-booting into XP to get USB devices to work, as is done on most other computers. Load Himem.sys to access more than 64MBytes using extenders. PharLap has no problem with 1GByte, the embedded controllers typically have 256MBytes.
ANYWAY! If anyone is using the ICOP or PC104 embedded systems, this might help. The CF-51 runs well under $100 (usually $50) used.
