I don't think that makes sense as if you were to want to access memory using long long pointers, then you'd want to recompile to full 64-bit anyway. There is the ability though, to use 32-bit pointers, and a full mix of 32-bit and 64-bit instructions (again, a recompile, but I guess a partial …

"Using the simplified segmentation model of 64-bit for segmentation support for 32-bit applications, matching what modern operating systems already use." I wonder if this means under this architecture, 32-bit programs on Windows x64 will be able to access as much memory as 64-bit ones, rather than …

7.0x (including OpenDOS on which Enhanced DR-DOS was based) were the real ones I think. Most 7.0x versions were similar, and I think 7.03 was the last one with a complete package of utilities. I don't know if anyone had actually bought a DR-DOS 8.0 instance. From what I remember that version was …

I think that someone as DREAMBLASTER should start to making this and sell it. Otherwise it would stay like nice dead on arrival great product. The problem isn't dISAppointment itself. It's that a motherboard must be designed with such a use case (ISA slot via LPC-ISA bridge) in mind to be able to …

Doesn't your boardview have net names? Yes, it does. Just that I need related documentation to be sure which pin is supposed to be connected to LPC_PD#. Connecting it directly will probably be fine, but resistors can avoid nasty surprises if you get something wrong. Particularly as the 3.3v rail …

I'm currently experimenting with an ASUS Prime B450M-A which I've found its boardview somewhere. The board's SuperIO (IT8655E) is a very small one that do not have LDRQ#, so it is left unused and could be accessed from an unpopulated pull-up resistor pad according to its boardview, which makes it …

You'll definitely need PCICLK, PCIRST and SERIRQ. Dunno what that 24MHz clock line is for but PCICLK is supposed to be 33MHz Guess it's not going to be easy for these boards then... requiring at least 4 wires, but still better than nothing.

Two questions: 1. Are you limited to one slot? Or can you have multiple ISA slots (e.g. one for sound and one for fdc)? 2. Does it support FDCs? These questions have been answered already. See here . As for the second question... since some SuperIO chips also have FDC (although they may not …

What superIO do you have? Most of them already contains two PS/2 ports. Your MB has any PS/2 on backpanel? My GB has only one. Some smarter manufacturers route both PS/2 to single miniDIN connector allows use Y-cable to split for both KB+mouse. But not GB, they was just too lazy to route 2 wires …

The resistance (ohms) of the individual resistors are too blurry to be determined from the photo so I'm not …
