Having the source there too made for some interesting reading this morning. Thanks for the original posting! Joel

If you don't, that's too bad. I do, and I really like the program. If you
want to rewrite it without 386 instructions, he included source.

Can anybody explain this? VP/ix uses the 386's "Virtual 8086 Mode" to emulate an 8086 pc. The new 32-bit (non-protected-mode) instructions are still available though as are the new segment registers (FS and GS). J. Barber Lanier Business Systems Atlanta, GA Just Say No To The United Way.

VP/ix requires a 386... the 8086 mode emulates the 8086 addressing modes (for the most part) but not the instruction set. It really behaves like DOS running on a 386 machine. Over the holidays I'm going to try to port the fractal program to use 32 bit arithmetic in the 287 chip, for older machines, and to CGI for Xenix people without VP/ix. I don't promise that either will get done, depending on what parties my wife decides to throw or go to ;-) I'll post the 287 version here if I get it. I have my own fractal program for Xenix, which could run on DOS, and I hand coded the innermost loop in 11 80287 instructions. Hopefully I have my notes on programming the 287, since the manual is just a starting place. -- bill davidsen (wedu@ge-crd.arpa) {uunet | philabs}!steinmetz!crdos1!davidsen "Stupidity, like virtue, is its own reward" -me

VP/ix doesn't really emulate an 8086. It emulates a superset of an 8086. It precludes you from executing protected mode instructions and from using 32 bit segments. When you're running in VP/ix, the processor is still executing the instructions directly, so you can use the 32 bit-mode prefix on instructions and it will work. Likewise, instructions like ENTER and LEAVE, which were only added to later processors than the 8086 also work. -- - john romkey romkey@asylum.uucp romkey@xx.lcs.mit.edu romkey@asylum.sf.ca.us Find the cost of freedom, buried in the ground Mother Earth will swallow you, lay your body down.

Can anybody explain this? Apparently, VP/ix kindly gives your virtual 8086 copies of the 32 bit registers to play with, too; fract386 doesn't do any strange and wonderful things with the virtual memory, it just does 64 bit arithmetic.

Can anybody explain this? I think it only emulates an 8086 pc in terms of memory addressing and the use of protected instructions... 32 bit arithmetic is no on the protected list so ADD EAX,EBX is ok. >--------------------+------------------------------------+--------------------- >Pim Zandbergen | CTI Software BV | Phone: +31 70 542302 >pim@ctisbv.UUCP | Laan Copes van Cattenburch 70 | Fax: +31 70 512837 >..!mcvax!ctisbv!pim | 2585 GD The Hague, The Netherlands | Telex: 32133 CTI NL ---------- marco

I got the fractal program and tried running it on my 80386 (acer 1100) in both dos-merge and in native dos and it just hangs as soon as i run it. No menu or anything -- just a hang right away...
