what

this is a different disk.

did two disks on my desk go bad at the same time? or is this USB drive A USELESS FAILURE?
ok I'm trying a third disk and if this fails this drive is going right in the lake
it wrote successfully! now I can install some MS-DOS 6.22
dang it. after all that time installing it, it can't boot.
it doesn't even fail to boot, it just hangs at boot

some stupid problem with partitioning/mbr, probably
yup. boot disk, fdisk /mbr, and now it boots fine.
now I can get some REAL work done.
god I love this ANSI art floppy disk
wait, you can't do that. that's illegal
this is not how Doom is supposed to run, man.
isn't this shit a 486? yeah, it's a 66mhz 486.
the fuck?
so why is it benchmarking like a fucking tandy 1000? an 16mhz 8086!
OK I fixed some bios settings and it's now as fast as a 25 mhz.
huh.
This cyrix really sucks, eh?
better? crappy, but better.
ok the chip is a Cx486SLC2.
That's really a 386... but it should be running at 50mhz. it definitely isn't.
So I can adjust the CPU speed by changing jumper 8... which isn't there. They hardwired it.
And JP9, which is also hardwired
JP10 isn't hardwired, thankfully.
so that means I can do 16mhz or 25 mhz.

and it's currently on 16mhz.

well, let's try 25mhz!
Better!
still not great, but it feels a little better.
I wonder if I could overclock this stupid 386. I could desolder that hardwired jumper and replace it with a real jumper...
this board is never gonna be fast, though.
it's got a 486-labeled 386 soldered to the board, and zero cache.
very very limited entry-level board, this.
ok maybe overclocking the 386 is a bad idea.
(I haven't done it yet, this is just how hot it gets at 25mhz)
It may also be the VGA card I'm using. It's an ATI mach32, which is designed for accelerated windows 3.1 use, it might be slow at mode X stuff
or mode Y. I forget which one Doom uses. I think it's Y

SolarWinds follow up. Very good tweet explaining what happened.


Basically what this means is that SolarWinds itself was exploited. Someone posted an infected update as legitimate (digitally signed), leading customers to download a bad update.

“Multiple trojanized updates were digitally signed from March - May 2020 and posted to the SolarWinds updates website” https://t.co/8e3bMFWXYu


FireEye then explains that infected organizations were approached and exploited. This is a separate Step 2.

At this point, information is already going to “malicious domains” without extra intervention, after the malware does nothing for “up to two weeks”
