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 Version 1.8 - small bug fix - improved alignment of test code and test memory - enhanced opcode fetch testing - check for presence of MSRs and subtle execution oddities (separates 386 CPUs manufactured by INTEL from those of other brands). - changed detection code for IBM CPUs (have MSRs built in). - changed detection code for CYRIX CPUs according to manufacturer provided code. - should detect CYRIX M1sc (5x86) - added NexGen NX586 detection code according to manufacturer provided code. - should detect new NexGen CPUs - added AMD 486/5x86 detection code according to manufacturer provided code. - should detect AMD 5x86 CPUs - detects INTEL Pentium Pro Version 1.8a - v1.8 introduced a heavy bug on AMD CPUs, fixed (I hate this 5x86 marketing stuff) - improved testing of DRAM page size - should detect INTEL Overdrives - should detect Cyrix 486DX4 - should detect TI 486DX4 - should detect IBM/ST 5x86 Version 1.8b - small bug affecting 5x86 and Nx586 CPUs fixed Future: - overall improvement :-) - less bugs :-) - fancy GUI interface - any other good and implementable idea
