It seems that it can see 4 cores, and only 2 work because NT4 Workstation supports only 2. But it's interesting that the CPU is recognized as J2670 which doesn't even seem to exist? It's J1900 in reality. Filename mps.png File size 34.75 KiB Views 365 views

My NT4 virtual machine (VMware Workstation 17 Player) recognizes 2 (but not 4) CPUs By default NT4 Workstation is limited to 2 CPUs, what happens with NT4 Server? There are also patches to circumvent the 2 CPU limit, but I have never used them. How many CPUs does the MPS 1.4 table report? Haven't …

Yeah sounds about right that hyperthreading requires ACPI. But this is for HT only, and a real dual-core CPU would work, right? My NT4 virtual machine (VMware Workstation 17 Player) recognizes 2 (but not 4) CPUs when running on Celeron J1900, which is a quad-core with no HT. I haven't tried to run …

If you're dual booting Windows 7 with (presumably 32-bit) Windows XP, then you don't really need a 32-bit version of Windows 7, because whatever has problems with 64-bit Windows 7 should run fine on XP. On the other hand, a 64-bit OS is the one that can utilize the full potential of your CPU, not …

When my HDD space runs out, I used to use hard disk compression, however. Either on file system basis (DOS/Win 9x, DriveSpace) or on OS basis (Win NT, NTFS file compression). I never used DriveSpace because it was horribly slow (at least on those machines I've seen using it) and it ate some …

Back in the day I never used "compressed floppies", just .zip archives (or better .arj and .rar). ARJ and RAR support splitting big archives onto multiple floppy disks, which was very handy.

The 4gb thing isn't real only exists on a piece of paper somwhere. It's in the design of the CPU and its 32-bit instruction set. Theoretically it should be possible to build a 386 mainboard with current tech that would accept 4 GB RAM. Just like current 64-bit CPUs support some astronomical amount …

Standard extension cables may not use all the pins needed for VESA DDC communication with your monitor. I checked the cable and it seems that pins 9, 11, 12 and 15 have no connection. This is quite bad. The cable is half-useless this way. And there's no way of telling if the cable is a good one …

How about a rescaler feature, where the output resolution will be forced e.g. to the current desktop resolution, but the game will be free to render in any resolution it wants, dgVoodoo doing the rescaling? This could fix some issues with equipment doing poorly with non-native resolutions, e.g. low …
