Just FYI, TDE has keyboard issues under VBox, so it's mostly useless there.

Actually, upon further look, it seems to only work for those two vi
clones exactly because of IDLEHALT.

Unfortunately, I am not competent enough to hack E3 very well, so my
weak attempts didn't seem to fix the issue there.

(Plus I don't like hardcoded "lines", always stuck at 25. TODO.
Although I did find a 186 instruction, which I consider a bug, so I
quickly fixed that to 8086-friendly, even if that's overall futile.
And I still wonder if WordStar keys are easier / more popular for end
users than vi. Oh well, E3 is much smaller than most editors, that's
for sure.)

Re: [Freedos-user] upper memory trick

[Don Flowers]

Has anyone tried "Installhigh=C:\FDOS\COMMAND.COM"
I have that working for a few apps (including DP and so far no issues, also
am loading CDROM drivers earlier in autoexec.bat and I can cram nealy
everything into upper memory.

Re: [Freedos-user] Which freedos on 486 (digression)

[Eric Auer]

Hi JAS,

indeed I am trying to motivate people to use TLS/SSL ;-)
There must be SOME browsers for DOS which can handle it!

Note that I was talking about Google Drive, not the basic
search engine. The Drive needs a lot of heavy JavaScript.
