I saw that module, looked at the code, and wondered if at that point it wouldn't be easier to just run a thin wrapper around the virtual 8086 code while just using standard virtualization extensions. That way it's just another KVM

You can support 16bit in long mode via compatibility mode (the bits are still in the Global descriptor table definition https://wiki.osdev.org/GDT as long as the long mode bit isn't set the, Sz bit can be used to indic

Looking at the 8008 wiki if the quotes are to be believed they were actually scared of performance. Believing that they would scare off customers buying intel memory (their main business at the time apparently) for their own in house proces

I am completely not surprised by this move, HBM2 solves a major issue for quite a few applications that live and die on high speed memory and assuming sapphire rapids has enough ports to make use of it optimally will make these an absolute

They did release it for the windows XP 64bit editions for AMD64. So no it was definitely released, it has rendering issues but it is there and works AFAIK. As best I can tell it was removed because it didn't fit vista's aesthetic

Actually 3d Pinball is available in the AMD64 Window XP 64 bit versions. It was not available (sort of... it's there but not actually installed from media) on IA-64 versions. There was a youtuber that dug into it (probably at the cost

So there are various Youtubes about this... but it was 'Windows XP 64bit-Edition' (yes 'Edition' is part of the name. This specifically refers to IA-64 and not AMD64. There are rendering issues on the AMD64 versions but

by leeter 5y ago
Given that the reason it was removed was IA-64 which isn't a thing anymore... this should be plausible. But also given where MS has gone with games as late I'd be surprised if they do. EA should just release all of Full Tilt! Pinb

IIRC it's a size and power thing. You can emulate most of what a ring laser gyro does with good accelerometers and that's the better choice for most devices needing long battery life and compact size. Ring laser gyros (while small

Also airplanes, satellites etc. The standard now is laser ring gyroscopes as they have no moving parts, are super sensitive, and very light in comparison to older options. Mentour pilot has an episode on how these are used in the 737. http

I think intel and IBM didn't expect the need for compatibility to be an issue. After all when the IBM PC was built generally speaking turning on and having a BASIC env was considered good enough. IBM added DOS so that CP/M custome

I wonder if the CSG-65CE02 wasn't an attempt to make C easier for the C6x/c128 line. Unfortunately it never saw the light of day except as a serial controller and isn't available today https://en.wikipedia.org&#x2F

Repeated exposure increases your chances of disease not serious disease. Increased Viral load increases chances of serious disease. Apologies if that didn't come across clearly.

No, exposure to the virus is like exposure to combat. You may not die, but the likelihood goes up the more time you spend exposed to it and the more of it you get exposed to. To keep with that metaphor a vaccine is like a war game, it won&#

DOS seems to have been the minimal effort choice of "It's like CP/M enough our users will be familiar with it" without actually considering those users. Now to be fair in 1981 that was "state of the art". The X

It's not politics its just that there is a dispute between ARM China and its parent, this is well documented. This complicates IP licensing concerning the ARM ISA in the world's largest market. I personally wouldn't want to d

by leeter 5y ago
It's complicated and annoying but yes. There is also the question of 'downleveling' a core back to real mode when the others aren't. But if you require UEFI and secure boot then you could bypass that and go to a 64-bit l

Or OS2 (ATMs) or DOS (an unbelievable number of PoS devices and other 'business ops' uses as well as industrial). Now to be fair... most of that market is already served by a vendor that doesn't make desktop CPUs most notably

by leeter 5y ago
So right now when an x86-64 CPU boots it starts in 16bit real mode regardless of everything else. The UEFI then has to set up a x64 protected mode env then the OS picks up from there. If you drop that backwards compat (e.g. 16bit, virtual 8

by leeter 5y ago
Eh I could still see a ton of application specific customers that would stick with x86. HFT for example: if they can get a chip with a few super fast cores and HBM2 on substrate. Perhaps mix the NIC in and turn the entire thing into an SOC.

IANAL, but the publication of the work is when the copyright timer starts under the '76 act IIRC. However, and this is a big however, because the (re)publisher is not the artist and the pre '76 act did not have automatic default c
