Re: Matrox Mystique Windows 95/98 driver hang

There's strange IRQ-related issues with it at this early WIP stage i've noticed on other boards (at least that's what the Powerdesk Diagnostics bring up), and the most stable setup right now is a ZP+Win95+4.10.01.4120 EDIT: Disabling the floppy drive in the bios can potentially produce a reboot loop...

Re: Recommended settings for Windows 98 SE on high end systems?

I've used 40-60gbs fine with Win98se guests just as i've had in 1999-2005. It's those older Socket3/7 BIOSes that were fussy about hard drive size heading into 7gb at best (many large drives had a jumper for limiting to that for compatibility reasons) though you'd also be able to install that EZ-BIO...

Re: Performance Degradation From Going Above a Pentium 233?

Yes, emulating faster CPUs require faster CPUs. K6-2 has 3dnow extensions, which some drivers and games can use and require even more CPU to emulate (on top of the faster clocks) Also the Windows desktop doesn't get along with dynarec so installing a HLT-spamming thing like "cooling tools" such as R...

Re: Needing help installing mouse and CDROM drivers in Win95 dos mode

The "proper way" back then would be dealing with whatever real-mode drivers your OEM conveniently supplied at install time, or whatever drivers your mouse/cdrom kit supplied on floppies. but nowadays you could lazily take OAKCDROM.SYS from the 95/98 boot disks, throw them in autoexec.bat/config.sys,...

Re: 3DNow!

Most likely the FPS gain's from the post-launch work on ref_gl.dll. Quake2 was not very multitexture optimized at 3.05's launch, and the Voodoo2 wasn't out yet (though, Carmack did have a pre-production V2 board in Jan '98)

Re: 3DNow!

The 3dnow! version of Q2 should be a separately obtained special v3.20 version and should display a disclaimer baked into the console background (as well as changing the names of the selectable renderers). Offiical Q2 patches are not 3dnow! optimized, and Q2 3.10 predates 3dnow (Jan 1998).

Re: Adding cd support to dos 6.22

*off the top of my head*
Try adding this to CONFIG.SYS

Code: Select all

DEVICE=C:\OAKCDROM.SYS /D:CDROM
and then you'll have to add this in AUTOEXEC.BAT (or a separate cdrom.bat batch file to run instead in case of memory issues)

There's still that Direct3D 6-7 primary device gap that VM software can't touch. Also as for VirtualBox, they're retiring the video device that brings 2K/XP OpenGL passthrough pretty soon. (the other newer devices don't have a 2K/XP guest additions driver (yet?))
