Not too bad, honestly. I think p7zip (several MB) took longer when using LZMA on my 486 (esp. compared to --best). But it really only matters for stuff you execute / invoke a lot. I'm not sure people use PING enough to be a problem. (But perhaps others would be more sensitive.) YMMV. Even WinXP has a penalty for UPX'd DJGPP stuff, strangely. So it's not just slow machines. (And this hurts when compiling, so you have to be careful of that, and it's been abandoned as default for a while now.) > The V20 makes the machine a little faster than a standard 8088 based > machine.

(Is my instinct correct here? I think I'm one of > the few nut jobs on 8088 based hardware, because it's fun!) Yeah, it's interesting but probably not practical. (So what? <g>) But yeah, there aren't many 8088 gurus / geniuses out there: Trixter, you, RubberMallet, DeathShadow. That's all I can think of off the top of my head. (I don't and never had any 808x machines, but it's a classic, IMHO, so I've often written 8086-only stuff, esp. since it doesn't hurt much, if at all, on newer machines.) > On a slightly off topic note, I need to learn to build FreeDOS.

The kernel is actually pretty simple to build, but you'll need NASM (0.98.39 on SourceForge has a 16-bit binary) and maybe FreeCOM binary as shell (dunno why). FreeCOM also should build with TC (haven't tried Bart's OW port in SVN yet). IIRC, my tweaked P166 took 90 secs. to build the kernel, if that gives you any (very rough) idea of how long it'll take. It's been a while, and it's not like I ever needed to rebuild that stuff a lot, so I can't remember. CONFIG.B -> something something. Anyways, if you run into trouble, just nag us, and some of us can help. :-) ------------------------------------------------------------------------------ AppSumo Presents a FREE Video for the SourceForge Community by Eric Ries, the creator of the Lean Startup Methodology on "Lean Startup Secrets Revealed."
