For this I have no problems in providing fully tested assembler code that accurately detects the following CPUs: cpu_8088 cpu_8086 cpu_V20 cpu_V30 cpu_188 cpu_186 cpu_286 cpu_386 cpu_486 cpu_Pentium "Pentium or...

Quick and dirty information that I found out from DOS98: Commercial life started around 1997 and ended up in 2007 approximately. During its life-time it appears that no DOS component...

So, then, false alarm. Would it make sense to recreate a few of those specific PTS-DOS API falls to achieve some level of compatibility? Or is this a case of...

Yes, probably not worth it, if only few cases exist and do not conform to the "standard" DOS API. A pity, but absolutely reasonable.

Hi, thank you for your answer, I re-tested it against FreeDOS 1.4 boot disk and indeed, it works, reporting FAT32. It is the official 1.4 FreeDOS 1.44 MB boot floppy...

Note that the following program will not report FAT32 kernel on OpenDOS 7.01 nor Enhanced DR-DOS due to the missing int 21h AX=7300h function. However, whenever it gets implemented it...
