The following is an issue regarding the mouse and VGA (some how) that I had while trying to setup FreeDOS on a newer laptop. I asked https://reddit.com/r/dosgaming, but ended up finding my own solution. This issue comes up about once a year or so on /r/dosgaming and I'm tired of having to spend 30 minutes hunting links to old posts, so here you go...
FreeDOS software errors involving mouse and VGA on 2008 Acer netbook Games and graphic editor programs that require VGA and a mouse will not run on my 2008 laptop/netbook. I have tried running ctmouse and changing the REM DISPLAY settings in the AUTOEXEC file, but it doesn't help. Has anyone gotten FreeDOS to properly run on a newer computer? I'm guessing there's a MOUSE.COM file I'm missing, but I haven't got a clue where to look. Please no DOSBox suggestions. I'm well aware, but that's not the point. SOLVED: dir mouse.com /s Pick one of the results and add to AUTOEXEC.BAT as "LH=C:\PATH\TO\MOUSE.COM" dir mouse.sys /s Pick one of the results and add to FDCONFIG.SYS as "DEVICE=C:\PATH\TO\MOUSE.SYS" In my case, I used MOUSE.COM from Visual Basic for DOS v1.00 and MOUSE.SYS from MS WORD 5.5. Even the touch to click works on my trackpad. Make sure to reboot. I picked the VBDOS version for MOUSE.COM because it was the largest version of that file, so I figured it would have the most bang per byte. It also seems to have fixed a lot of program's display issues. But, I also changed the EGA code numbers in DISPLAY="..." inside of AUTOEXEC.BAT to 437 (US) instead of the default 8xx one (can't remember the number).
2021/01/18 Edit: The EGA mode number was 858 before changing it to 437.
