I tried with HDPMI32 -r and HDPMI32I -r but for some reason Doom hangs at startup (init head up display text message). Even If I don't load aweutil at all. No matter what memory manager loaded, tried with himem.sys, jemmex and without. But it ramdomly works with cwsdpmi -r and aweutil but not usable, sometimes it hangs at Doom start sometimes a bit later up to 10s after game start. Until it hangs it plays sfx and MIDI fine.

I also found I made one mistake using aweutil.
I had
aweutil /s /em:gm
at one line in autoexec.bat and that is bad. It should be called separately.
usually good to place only aweutil /s in autoexec and call aweutil /em:gm later when loading game that needs MIDI emulation. Also because loading big soundfont take several time, huh 8MB takes 20s and it's not due to slow HDD (maybe it loads via slow PIO through ISA bus)...

After I fixed this the DOS32AWE started working as expected, Doom, Doom2 and Blood plays MIDI fine with loaded soundfont. With 8MB bank it sound better than with default 1MB ROM. Great, only one anoying thing remains that DOS32AWE contains artifical ban for v86 mode even if not strictly necessary because older version runs without this restriction but they vanished with the author...
