For a long time using a computer means dealing with spinning rust, and while SSDs exist nowadays...

That being said at least in one case “The pedestrian push buttons have been deactivated and crosswalks are currently operating on a timer”.

AFAIK while AMD didn't produce the 387 there was alternatives from for example Cyrix and IIT at the time.

On the other hand, Xorg pulled the original -vga driver quite a long time ago because it was quite a lot of code.

There is a MS13-xxx bulletin that had a bug where full screen DOS was completely broken when /NOEXECUTE=OPTOUT was set in boot.ini

Part of the reason why I pay attention to Marginalia search is the hardware problems it shows. There are now some good papers on SSD based search engines.

Part of the point of SSD based search engines is they are much easier to cold boot as well.

Part of the problem is that Google was designed when PCs booted from spinning rust and a fast CPU was a Pentium II.

"This must be passed to the FPU interface, which acts somewhat like a DMA controller and contains its own base and limit registers." What may be fun is the coprocessor segment overrun exception.

That is why I said "without the F1 prefix".

The fun thing is that 0F 04 (without the F1 prefix) would have been faster than triple fault or reset via the keyboard controller.

I wonder if the main concern is buying Windows licenses via volume licensing and paying for Software Assurance.

The patents has recently been expired.

The difference between Cat5e and Cat5 is very little.

The Compaq is IBM PC compatible but uses a different HAL for SMP support. You can see all of them by looking at what NT4 shipped with for example.

DDR5 supports 24Gbit chips, though they are not common yet.

Part of the reason why I wrote about CompatTelRunner is that Billy O'Neal was complaining about it on Twitter.

Intel phased out the UEFI CSM from new platforms in 2020-2021.

When PCs still needed spinning rust to boot from. Even SATA SSDs are not as good as NVMe.

In fact, you can't really run any other legacy option ROMs without legacy VGA support. You can run legacy SAS option ROMs for example and still do UEFI boot because of similar support for Int13, but to even run them require VGA text mo

A lot of the difference is in things like keystone jacks and patch panels, as this is where far end crosstalk is most likely.

The differences are minimal. There is a good article on this topic: https://www.flukenetworks.com/knowledge-base/application-or-...
