MoSlo, Sierra under DR/PC DOS (A.K.A. FREE DOS)

[glendower]

Okay, I found some of my old sierra games and decided to try them out on my DOS laptop running FREE DOS (which used to be known as DR or PC DOS-- an MS-DOS clone). Of course I'm getting the chk sum error on my MT-32 (except in Tie Fighter, it must not actually load any sysex, right?). To test SQ3, I used moslo to drop the speed down to the equivalent of an 8086 (under 1%) but my system hangs. Actually, the system hangs when I try to start any program with moslo.

I see in the readme that moslo works most bestfully under true MS-DOS, but I want to know if anyone has successfully run moslo + sierra under FREE DOS and if so, how?

I guess I should just hook everything up to my hulking MS DOS box, but I've already installed everything on my laptop! I'm sure I'll give it a shot, but I was hoping to get it working on my laptop so that I could easily take games to my friends' house (the wife-side of the friend-set has never seen T7G, and I'm sure she'd like it a lot). I suppose I could install DOS 6.22, but PC DOS is FAT32 compatible, and I'd have to reformat the system and then get MSCDEX working correctly--- FREE DOS automatically installs CD drivers AND can install from CD... it's pretty handy.

Also, how far should i expect to under-clock a P5 133MMX to get it to work successfully with my MT32?

(gateway 2000 Solo 2200, Pentium 133MMX [a few do exist], 56MB RAM).

Maybe it would be easier just to track down a CM-32 or 64... <sigh> a 64 went for 20 bucks on ebay... I forgot to bid.   :wink:

P5?

I run moslo on a PII 333MHz system -- and often use MoSlo.  With HEART OF CHINA'S arcade sequences, I found using /40 to work well.  That's using Win98's DOS prompt.  I also have MS-DOS v6.22 installed (but not all my sound devices are working under real DOS, at the moment) and find the same MoSlo setting works well.

I recently retired my Pentium 133 MHz system, where I don't remember using MoSlo with games very often.  But then, I didn't play a lot of them on that system.  All of my systems have had a MT-32 connected.  MoSlo has always taken care of MT-32 buffer overflows for me.  Alternatively, I often disabled the system's internal cache to slow the PC.  Either way was effective.  

I haven't used Dr. DOS in a very long time; don't remember why I ever used it to begin with.  I remember having to rely on IBM's PC-DOS for a couple of games, back with my first Pentium 90MHz.

Thanks for the reply. I'll try putting MS DOS on there and see how it goes. I'm just having a hell of a time getting my MT 32 to work for games. It works in some (tie figter, Doom, and in MIDI player) but sierra games hang in protest with MT32 selected (riding on an AWE32... it seems like I remember reading about problems with the midi port on those things...). On the laptop I get Chk. sum errors and on my dual 166 the things don't even start (on the lap top they'll start with sound blaster selected).

Sorry... too much time on comptuer forums maybe. I was referring to the core numbers... P3 = 80386, P4 = 80486, P5 = Pentium, P6 = PPro - Pentium III, P7 = Pentium 4, etc. Habit i guess... heh.
