Hey guys I've recently been repurposing an old P4 machine into a retro gaming pc and am running into an issue with the integrated graphics. It is an optiplex 107L and a system originally designed for windows XP, currently it's running stock hardware with windows 98se installed but I have a Aureal Vortex 2 and an Geforce FX 5500 on the way (no agp or isa slots unfortunately). In the meantime though I'm having issues getting dos programs to play nice with the integrated graphics. When I first got the machine up an running with no graphics drivers I was limited to 16 bit color and 640 x 480 but dos programs would run full screen no problem but after I installed the Intel graphics drivers, windows 98 programs are working fine and I can change the resolution but I get a distorted or no picture when running dos games (using Blood to test) or even when rebooting into DOS mode. Does anyone have any experience with this? Thanks in advance.

If you boot directly into DOS by hitting F8 during boot or by adding a BootMenu=1 entry to MSDos.sys, are the graphics still messed up? That way the Windows drivers wouldn't get a chance to screw things up.

Oetker, that seemed to solve the garbage video problem I was getting but now I'm having trouble with the sound 🤣, it's the SB0200 of course so I think I'm just going to wait until my new parts arrive before I put more effort into this. Thank you for the response though, good to know in the future.

forget about plain-dos, use games that work on win98 and use the integreated audio and the sb emulation in win98se.
i highly recommend the i865gv because it has a fantastic image quality and a very good support on lowres-vesa for demos.
beside that the i865gv supports the old texture-compression-routines (perhaps the 5500 too), so unreal 226+ in 800x600
32bit looks fantastic (S3TC-Textures). It also offers hardware-scrolling on Jazz2 if choosing 640x400 8Bit and hardware-mode.
The scrolling will then be as if you are playing on a console!

It also has most features on the early O.S.D.M.-Tool, so you can bouild your on Intros that look really good!
