MuPDF.exe. It ran right out of the box -- i didn't need to tweak
CRT.CFG. (Intel 865G video chipset on m/b, VBE 3.0, tweaked with
VBEHz on bootup.)

Display/scroll speed is fine for me (2.8ghz P4), but i can see
how it could possibly be an issue on slower machines. I don't
think DOS can use video hardware acceleration.

F1 keypress displays a superimposed list of keyboard keys and
their functions. It fades in a few seconds without the need to
press another key.

The CRTC.CFG file has a comment line that sez: "set calculated
CRTC data for current videomode, for calc. run GTFCALC program".
"GTF" stands for "Generalized Timing Formula", a VESA standard
for CRT systems:

http://en.wikipedia.org/wiki/General_Timing_Formula

Unfortunately, the link on that page to a spreadsheet on the VESA
site that helps you calculate the params is broken. However, i
found a copy here:

www.cs.unc.edu/Research/stc/FAQs/Video/GTF_V1R1.xls

You must be messin' close to the hardware, eh?

So, wow. An up-to-date, self-contained PDF viewer for DOS.
Totally awesome. RayeR... you da MAN! (And that was a *really*
quick turnaround time.)
