As many of you I am going through the struggle of getting the most out of my MS-DOS memory, but due to a SCSI Controller (Adaptec) I am using 2 drivers that are killing my memory: ASPI7DOS.SYS - Is taking 25Kb of memory ASPICD.SYS - Is taking an additional 12Kb And this is before I load MSCDEX that …

If all people want to do is ask questions for their own projects then currently milliways works. It doesn't really work for me, because there's so much else going on in that forum I rarely ever look at it - I can't keep up with all of the new posts. If there was a forum related to software …

Yeah, I was hoping for a forum for not just release announcements but also discussion of development topics, something which would include threads like the following (which are mostly recent I think, I didn't go back very far to find them and only checked a few forums): https://www.vogons.org/ …

Like it turns out Windows NT 3.x lacks the WM_SIZING and WM_EXITSIZEMOVE events - how do you emulate them with the window messages that NT 3.x does provide? IIRC there is basically a single forum post from 15 years ago visible to google that discusses this subject at all and it points to some …

For those that have a AIXXCO adapter working at 720x400@70, can you please open it up and check the IC inside? I think they've """upgraded""" it and it's now using a MacroSilicon MS9288C instead, which doesn't seem to be capable of handling it. Mine is also AG02-EX (it says 2103 under that, which I …

One possibility is to have an intermediate machine which translates protocols, e.g. a Linux machine which mounts the desired FTP server(s) (see e.g. https://en.wikipedia.org/wiki/FTPFS ) and then re-exports them to the DOS machine via a protocol it does have a client for (e.g. EtherDFS, Mars NWE so …

Anyway, I think another problem might be that FTP usually requires a copy operation. Other types of networks/network drives can read files partially, without the need for complete file transfer. The copy operation could just be to a buffer in RAM rather than to disk, and I imagine that with FTP one …

On Ubuntu I've had good results cloning old hard drives and restoring the images to CF cards with Gnome's Disks utility . It can create and restore disk images. Don't know if it actually uses dd tool internally to make and restore images. That reminds me: I wonder if partclone has any smarts for …

I'm not sure, but I think that if you were just using DOS, another possibility would be that you could pick some geometry in the BIOS which has a greater number of heads and sectors per track than your old drive, and just waste the additional capacity. For example, if your old drive emulated 13 …

Sometimes the BIOS will give you a few different options for what CHS geometry to present when the drive itself is LBA, but I think they're generally ones where the heads and sectors per track are either set to maximum (16 and 63 if I recall correctly) or some power of two, whereas I think old …

Very interesting Doshea ! that's another great alternative to try. You're a great scout. How do you find all this?

I suppose it's cheaper to register a cracking program than to individually register all the programs that it can crack, so people might still register it? :) Back on topic, I had a look through the book DOS Power Tools (I'm not sure if it's possible to read it online) and found out that PC Magazine …
