Hi, I've got an OLD Tandy 1000 (not '1000A'), and have a hard-drive-on-a-card inside it from the Hard Drive Specialist, and a Tandy 286 Express card in it. There is (was) a ROM BIOS upgrade for the 1000 a while back which I never did. I am experiencing all sorts of wierdness (have been for some time, just too lazy to fix) from having "Invalid COMMAND.COM... System Halted" to hanging the system on boot-up. I should also add that this has only happened with upper DOS versions (> 3.0), and I have been told that the original ROMs (on the motherboard) do NOT work with the upper DOS versions (the upgrade is required). However, I don't think te motherboard ROMs are being used, since there are ROMs on the hard drive card. These are the ROMs I think I should replace, not the ones on the motherboard. What I'd like to know is: a) Is Hard Drive Specialist still around? b) Was there an upgraded BIOS ROM from them? c) Would replacing the ROMs on the motherboard do any good? d) Are there any suggestions? (Please don't tell me to add: "COMSPEC=c:\command.com or the SHELL environment variable for the Error listed above. These are NOT the problem(s). Thanks) Thanks in advance to any and all responses.
