Hi, this may be a rather stupid question, but is there any way to "embed or burn" DOS into the ROM of a computer so it boots w/o a HDD or FDD? Just wondering. I have a Tandy 1000 HX that has DOS in the ROM and it acts as drive C:, so once you delete something using the DEL command, you can't just copy it back from a floppy.
THANKS A LOT!

There is a good DRDOS manual available:

Though it should be feasible to use most versions of DOS..........

I have never heard of deleting dos from rom with the del command, also I think the it is only possible to run dos from rom on computers that came that way, I had a tandy 2500 ex that was that way, too. (I now have a tandy 1000 ex that is bsaicly what you have, but no dos in rom)

If you can delete it, it's not a "ROM." That's the whole meaning of "ROM" or "READ ONLY."
I once had a little laptop with a "boot ROM," had Dos 3? 4? xx and a small version of "laplink lite." (NEC Ultralite)

What you did, was format the "C" drive from the boot rom (I think) and then you had a "D" drive for storage. Both these were virtual drives in memory, and it had a sort of memory battery to keep the Ramdisk's memory.I don't know anything about how you would set one up, but you would have to have some device that you can "boot from" and in the case of many older machines, there simply is no provision for booting from any type of ROM. The machine, far as I know, would have to have something right in bios to cause it to "look" for a boot device, same as older machines will not boot from a CDROM, or a "network" boot. These things have to have their basis in BIOS.
There are many, many industrial applications for ROM devices. I used to install SRX/Motorola "Centralink" 911 phone systems--the system for the actual phone "switch" was a ROM system with a 286 processor. You programmed the system through a cable and computer.
