Version 1.0:
- high resolution time measurement ok.
- detection of L1 cache ok.
- detection of L2 cache ok.
- CPU type detection ok.
- partial implementation of video performance tests.
Version 1.1:
- L1 cache code improved.
- L2 cache code improved.
- AT cache detection added.
- CPU type detection reworked.
- full implementation of video performance tests.
Version 1.2:
- L2 cache code improved.
- DRAM page size detection added.
- cache line size detection added.
- video info added.
Version 1.3:
- different device driver used to be WARP compatible
Version 1.3a:
- nasty bug in preloading code pages => total system lockup (fixed)
Version 1.4:
- L2 cache code improved.
- CPU type detection improved.
- DRAM page size detection improved.
- DRAM interleave detection added.
- results layout depends on presence of L1/L2 cache.
Version 1.4a:
- CPU-ID bug fixed
Version 1.5
- CPU type detection reworked (more CPU types, more reliably)
- more robust to different environments:
works without device driver -> less details
works from a boot floppy -> no video testing
- much smaller critical code with disabled interrupts should remove any
chance for lockups due to page faults
- fixed bug in L2 cache code (affected Pentium only)
Version 1.6
- another CPU-ID bug fixed
- minor code reordering to improve L1 cache detection on Pentiums
- added testing of opcode fetch from L2 cache
- added capability of opcode fetch testing on CPUs with harvard architecture
(sorry, this needs much bigger code)
- added 'more' option
Version 1.6a
- bug in CPU type detection fixed (could not separate 386 type CPUs)
- added test for FDIV bug
Version 1.6b
- FDIV test introduced a weird bug, fixed (sorry, I don't have a Pentium)
- video chipsets now detected according to the *.DSC files, not SVGA.EXE
Version 1.6c
- UMC U5D, INTEL 486DX2-WB-SLe, AMD 486DX4 and AMD 486-SLe detection added
- INTEL 486DX4 detection fixed
- CYRIX detection code changed, no reply from testers so far
- ALI graphics chip set detection added
- italian language version added
Version 1.6d
- CYRIX detection code fixed, works now
- changed opcode fetch test according to new infos on Pentiums
- reworked CPU elimination code
- improved bus size detection code
Version 1.7
- major code shrink
- the results display contained many unnecessary figures
- the figure for memory -> video transfers was wrong in case of cache misses
- CYRIX CPUs have peak performance with 4 byte opcode fetches, INTEL with 6;
test both, report maximum
- check, if virtual mode extensions in INTEL CPUs are present and enabled
Future:
- overall improvement :-)
- less bugs :-)
- fancy GUI interface
- any other good and implementable idea
