So I should be installing DOS 7.1 and not 6.22? This also explains why my Windows Workgroups 3.11 can't see the 32GB disk? Yes, Dos7.1 adds support for fat32, int13 extensions and partitions and disk sizes up to 2TB. The limit is dependent on the motherboard bios. If the bios supports 48bit lba , …

Is this just a drawback of any card that use a genuine OPL3 v creative CQM chips (which appear not to be speed sensitive). I have only used my Vibra (with real OPL3) on a Pentium MMX 166 and it had no speed issues there. However, I did test a (PCI) Yamaha YMF744 on an AthlonXP 1700+ system at full …

Around 2001-2002 onward bios' from Award and AMI etc started supporting booting from USB Mass storage devices. It will then treat the usb device as a hard drive accessed via INT 13h extensions seen as 80h for first hard disk. This is very good in Dos7.1(fat32 + unlike dos 6.22 it also supports int13 …

I'm thinking about building a modern PC especially for DOS... So, what do I need? FreeDOS still seems problematic... so, the recommended version would be MS-DOS 7.10 from Windows 98SE, right? What's the maximum usable disk size? Is there any additional software necessary, like some HIMEM/EMM386 …

Doesn't setmul have exactly the same options when using a non-mmx Pentium 75-200. Things like Disable pipeline, branch prediction etc. or do P1 MMX offer even more slowdown options v Pentium P54C. Not every Pentium CPU has the "TR12" switches that can be used by SetMul. I have one Pentium 166 CPU …

You could try pressing ctrl+alt+numeric key minus to slow the system down. Not sure if this works on a Pentium though. Is that key combination universal or model-specific? IMHO that function was not available on every computer. I remember in the early Pentium era this was on Intel's own branded …
