And that was the solution. Running SLOWDOWN /X slows down my PC enough that
the installer is able to install Wolfenstein 3D. ("/X" is "XT" speed, so
it's *really* slow. Probably overkill.)
But like the report on BTTR, I can't run Wolfenstein 3D. I've tried a
number of different combinations: (I am running RC5 on QEMU on Linux)
. With and without SLOWDOWN (attempted SLOWDOWN /MHz486:66 and /MHz486:133,
and SLOWDOWN /A)
. With and without JEMM
. With and without FDXMS
. With and without loading any drivers[see note]
The results are the same: the program flips into graphics mode, then sits
there. It's like it's frozen.
I haven't tried running Wolfenstein in many years, so I can't remember when
(if?) I ran this before on FreeDOS. But I think I must have, at some point.

[note]
The default config I've been trying most of the time has nothing loaded. My
FDCONFIG.SYS:
SET DOSDIR=C:\FDOS
!COUNTRY=001,858,C:\FDOS\BIN\COUNTRY.SYS
!LASTDRIVE=Z
!BUFFERS=20
!FILES=40
!MENUCOLOR=15,1
***and some menu stuff here .. but I'm just showing the lines that get
run***
SHELL=C:\FDOS\BIN\COMMAND.COM C:\FDOS\BIN /E:1024 /P=C:\EMPTY.BAT
And my EMPTY.BAT:
PATH C:\FDOS\BIN
