- Notes for PVW386 BETA 0.5
- Based on DKBTRACE
- by David Buck
- -----------------------------------------------------------------------------
-
- This is a 32 bit version of PVRay. It REQUIRES a 80386SX, 80386DX,
- 80486SX or 80486. A math coprocessor is not required, but it is recommended.
-
- My preliminary benchmarking shows this to be about 30% faster than the
- Code Builder version on my 80486.
-
- This is BETA version of PVRay compiled with WATCOM C386 8.5. In this
- version, auto-detect for VESA adapters has been disabled. The rest of the
- autodetect routines may be suspect as well. Please let me or the Persistence
- of Vision group know as you determine that it works with your adapter
- (or doesn't). This version does have the PRIOQ.C fix.
-
- The WATCOM C386 contains a royalty-free extender, DOS4GW.EXE. The extender
- is a restricted version of the 386 extender from Rational Systems, Inc.
- PVW386 needs to be able to find DOS4GW.EXE in either the current directory
- or on the PATH. DOS4GW can also support virtual memory. To enable virtual
- memory set the DOS environment variable DOS4GM.
-
- SET DOS4GVM=maxmem#R deleteswap virtualsize#V
-
- where R is the amount of 'Real' memory to use and V is the amount of 'Virtual'
- memory to emulate. Both values are in Kbytes.
-
- When I need virtual memory, I use:
-
- SET DOS4GVM=maxmem#8192 deleteswap virtualsize#32768.
-
- DOS4GW is compatible with DPMI, VCPI and XMS memory specifications.
