Ok i have checked your site: http://rayer.g6.cz/os/os.htm // czech only There is interesting info, that DR-DOS could be run from same partition as Win95 and other DOS and there is more info - that there are system files - ibmbio.com a ibmdos.com, and configuration file could be named to dconfig.sys …

Ok, i made DR-DOS 7.03 multitasking working - its working in not text videomodes, because its clever enough to switch to textmode for Taskmgr. To make it working you need to run taskmgr which is in DRDOS directory, it would say you that it needs to run share.exe which is same directory, after that …

And... they all worked, except Turrican 2. Pure DOS, standard driver and SB mode. Ishar 3's sound init is apparently speed-sensitive, so I had to slow down this beast of a processor in order for it to work in this game :) It turns out this Pentium 133 rig can be a good platform for verifying …

Some floppy images are -uhm- "compressed" in the sense that they aren't exactly 1.44MB in size (not to be confused with compressed WinImage *IMZ images). Opening them in WInImage and changing them to 1.44MB often helps with troublesome emulators (PCem, VBox, etc.) Or try emulators like Virtual PC …

Ok i tested new ESSinit: QEMU + JEMM - same results EMS with ATI MACH 64 - Doom 2 - no fx, noisy sound, Blood - is running no FX, Descent II is the same, Quake I + Carmageddon - still same noise. So still nothing.

That is strange - it does on my machine. Have you tried using the standard EMM386.EXE instead of JEMM? If it freezes the computer - try using the following switches ( ruthan , you can also try this line in your config.sys to see if it will fix your EMS situation): DEVICE=C:\DOS\EMM386.EXE RAM I= …

I got the best result with DR-DOS 7.03 task switcher that can switch even some protected mode programs/games, If I remember I ran 2 instances of Quake there :) Ok what about DR-DOS 7.0.3 modern HW / games compatibility, make sense use it instead MS-DOS? Update: I wanted to try DR-DOS 7.03 in …

Back in the day I had a hardware solution for this, I had bought a multimedia upgrade kit that bundled a sb16 with a cdrom drive. The cdrom had an audio cable which fed directly to the sb16. I’m trying to remember if it was a separate play button on the cdrom or if you did either a long press or …

My vague memory recalled that DR-DOS TaskMAX was a pretty decent DOS task switcher bundled free with DR-DOS 5.0 and 6.0. If you do not insist on MS-DOS, then perhaps you could check out DR-DOS. It really depends on Games and modern HW compatibility, i never used it. Regarding of last Phils video …

i actually gave up on the live yesterday with the assumption that it just wouldn't work. after reading around - it seemed that the yamaha YMF724 was a good option (due to it having a built in OPL3 chip?) Turns out i had one in the garage too! The yamaha still needs emm386 and if i have over 512MB …

The list is translated as follows: all games fail in TDMA, "Windows" means WDM Solo-1 drivers, and "WBDMA" means "111". Ok what about SB and Adlib settings, which games are working with Adlib only? And what is exactly Windows value - Does it mean that pure DOS wasnt tested, or that is not working? …

ideasman69: You probably need to set frame EMM386 parameter to D000-D7FF. As far as i understand it, umbpci is only for Real mode (Himem only) and cant be combined with EMS / JEMM etc.. For more knowledge look at this post: https://www.vogons.org/viewtopic.php?f=61&t=61044 // Search for text Dos …
