Re: FPU on emulation of pre-486 machines...

Hello. I far as i know 287 and 387 SX/DX emulation was added in 86box, at the moment the Cyrix 486 DLC/SLC, variants and 8087 are not emulated. I tested the emulation with Windows 3.1 in MR 386 DX(it´s good because Windows don not need to emulated the FPU) and Award 286 with Windows 2.11/286 and Wo...

Re: Dynamic recompiler and UNIX

Many non-Microsoft operating systems have major issues with PCem (and 86Box), most particularly on processors where Dyna is enabled. In most cases, turning off Dyna will fix that (at a speed cost, of course.) Confirmed for AT&T SysV R4.2, ESIX, 386/ix, Interactive (which is the successor to 386/...

Re: Feature request: revamping config files

Correction: Bad idea, OBattlet, for reasons I just explained to you... It would be good if the Configurator (which usually is a GUI) 'compiles' the resulting configuration data into a machine-readable optimized data set (binary, structured ASCII text, etc) so that the APplication itself can just bli...

Re: Feature request: revamping config files

Bad idea, Sarah. Although often separating the two is a good idea, in this case, with an ever-changing (so, very dynamic) code and feature set, you'd be splitting up knowledge about that into two programs, and that is going to be asking for trouble.

Re: Introduction && issue with Floppy

@vbdasc: well, #1 is now fixed by Sarah - we can turn that smartness off. :P And on #2 ... yeah, it is, but only if the hardware (or, in this case, emulated hw) cooperates ;-) Those 'cards' work fine, until you scroll the screen. Thats when junk appears, which makes me believe we are scrolling into ...

Re: Introduction && issue with Floppy

@SarahWalker: MDA, Hercules and CGA tried, all showed the same-ish behavior. I think I remember the CGA worked "sortof", the others failed to properly "wrap". As said, OTI VGA works. Others not tested. Also - quick dive into the sources show a lot of GNUism present. Slowly going ...

Re: Introduction && issue with Floppy

@SarahWalker: I will do some work to see if I can get this to behave on VS. I don't like VS itself, so will mainly work (first) on getting it to compile using the commandline compiler. Once that is done, we can add a VS project setup I guess.

Re: Introduction && issue with Floppy

@Battler: True, but older systems like Microport SysV/AT, Xenix, etc, etc, Minix, and even early Linux do not use a BPB at all, so its pure "luck" if the current code catches it or not. With empty file systems, this block is all-zeroes, and so the BPB code catches it and uses the image fil...

Introduction && issue with Floppy

Hi All, Quick intro: I have been in software and hardware development since, oh, 1985 or so, and now that I am semi-retired, can finally spend some time on projects that I never had the time for, and which need cleaning up. Its that horrible, nasty feeling that you did not fully "close" a ...
