It's not that bad, IMHO. That "it has to switch to protected-mode and then do a reset to get back to real-mode" thing is outdated information. Himem.sys (~MS-DOS 6.x) has two code paths. One that uses LOADALL (286), one for the 386 and later CPUs. isn't xms usage limited to manually copying data …

Thank you for you reply. :D I wouldn't call it thinkering (in the usual sense), that PC rather is my development computer. I've got all my DOS compilers and personal software projects on that machine, hence I'd like to try some 80186 or CP/M / 8080 code (22Nice). That being said, this PC is my one …

I connect all my machine from 286 upwards and macs from lc475 upwards to my NAS in order to transfer files. In plain Dos I use the MSClinet30 (TCP/IP) and TCP/IP is installed within W3x/9x and AppleTalk for the macs. I wish that I could get that to work. :) Someday, I'll try to connect to my QNAP …

Jo22, I think the BIOS tests the PIT chip by measuring how many timer ticks it takes to execute a certain piece of code, and you get the error if it is not within tolerance. Most likely the V20 uses a different amount of clock cycles to execute that piece of code and thus the BIOS thinks PIT has a …

.. or you could use it for raytracing. Or orbital calculations (STS+ supports FPUs). Or as a music player for MODs. Or for amateur radio use (JV-Fax/EZSSTV, Hamcom etc.). Windows for Workgroups 3.10 also works on a 286, though it has limited funtionality there (can only use existing network …

Little update. I decided to build a little shield for the RAM chip, to make sure I will not mess up the wiring on the ISA card. Maybe I can get a few parts on Friday or so. I'll post some pictures once I've got things together. 😀 Edit: Got them. 😀

I think the same as tayyare. Looks like an ordinary floppy cable from the late 80s/early 90s. It should support two floppy drives, with either a modern or classic connector (edge connector). If there''s a coloured cable (often red) on one side of the ribbon cable, then it is marking the side were …

As much as I like old HHDs, I have to agree. Old HDDs often have the highest power draw, expecially the power surge during start-up/spin-up phase. Some of them even exceed the PSU ratings by default (for a short moment, which new PSUs can handle, but aged ones not so anymore). So if someone has an …

My guess is that they don't do that anymore because of licensing issues. Back in time, games were originally only sold once -or twice- as a physical release by one publisher/company. Since then it has become common pratice that games are re-released (compilations, on-line releases) and license …

Also, you don't need to make your own FAT 16 partition, FDISK will just ignore anything beyond 8GB. Also a single 8GB partition in FAT16 is incorrect for DOS use. Biggest partition possible in DOS 4-7.0 is 2GB, but you can make 4 of them to have access to 8GB, so you'll need to re partition your …
