why are there jumpers on the front panel audio connector.
well im running out of jumpers to toggle and still no actual sounds
asus website says the 2400+ is validated since BIOS version 1004/1006 (depending on the CPU revision i guess). is it possible that if my BIOS isnt up to date, the board doesnt get far enough to even beep?!
the CPU stays ice cold even with the board powered on for a while. for whatever thats worth

this person https://www.vogons.org/viewtopic.php?t=56372 mentions about their build that

"Its not flawless, but given the power situation with Socket 462 and Modern PSUs, I feel this build is running great."

so there is some sort of situation that i should probably be aware of

Socket 462 mATX build: modern, silent, and future proof \ VOGONS

"Unlike modern systems which draw mainly from +12V rails, Socket A systems draw most of their current from the +3V and +5V rails." https://www.reddit.com/r/buildapc/comments/bl0oup/psu_suggestion_for_socket_a_retro_gaming_pc/

unclear if this should be expected to be an issue at the point where im just trying to get through POST, with no discrete GPU installed

"Make sure your PSU has at least 20A on 5v for Slot A and early Socket A boards." https://www.vogonswiki.com/index.php/Athlon_Motherboards

mine (Corsair CX650) does have exactly 20A

Athlon Motherboards - Vogons Wiki

i plugged in three HDDs just in case putting some load on the 12V might change something. it did not
the most suspicous thing about this to me is the CPUs not warming up
i was talking about this project with a friend on NYE and he asked which socket i was working with. when i said Socket A he was like "oh nooo you really shouldve gone with Intel for this time period" and said there is no end of weird issues with Socket A stuff. he may not have been wrong

i was hoping to come away from this with some clues as to which of my existing parts may or may not be functional. but now i just have more parts and even more uncertainty

not to mention less money

!!

this person tests Socket A CPUs with different PSUs, and finds that high TDP CPUs fail to POST with the newer PSUs which have weaker 3.3V/5V rails. my Athlon XP 2400+s are definitely on the power hungry side so i suspect this is what is happening on my system too

Can your PSU handle Athlon or Duron Socket A processors?

YouTube
i found a cheap a Duron 700 on ebay and will be testing that once it arrives
if i had known about this stuff in advance i probably would have looked for socket 754 gear or something lol. but im gonna see this through now
i guess picking possibly the most cursed CPU socket to work with is very on brand for me anyway

we are so back

in goes the Duron 700

so i powered on and got the first signs of life in the history of this project as the pc speaker started doing the "no ram detected" beeps. i powered back down, installed the cpu cooler and... back to nothing at all. did i kill it? 😭
trying the other mobo. its the one with no pc speaker so i gotta hook up the scope again. however there is one notable difference already: the cpu gets hot in this one (i burned my finger)
todo get a thermal camera
well, nothing on the pc speaker again and there is also a slightly worrying smell. i guess it was not meant to be
the burn is also quite painful so i am giving up for now
this sure has been a way to spend money and time
the blister from the burn has calmed down a bit with the help of a big blob of moisturizer. i am somewhat typing-impaired for now though
im thinking i may cut my losses and give up on Socket A after all. im eyeing a very tempting Socket 754 board with CPU and RAM all bundled and tested
it is interesting to learn that the 12/5V issues go back a long way lol
a Socket 754 board appears
but lest life become too easy, the IDE connector placement here ensures that a 24-pin ATX plug absolutely will not fit
also i still need a cooler
24pin to 20pin adapters are luckily available locally. DOS booting next week???
also this board is the bigger mATX variant. do i have standoffs to accommodate that? ha ha ha of course not

no wait i do!!

"PC ???" bin saves the day 😍

ive installed the board + i/o shield, put in a CMOS battery and thats about all that can be done today
curiously it seems that both the cooler and adapter are ready for pickup now despite it being saturday. DOS today???
cooler installation is a bit puzzling. the caps get in the way of the clips
i could unscrew the bracket from the mobo but then it is impossible to screw it back with the cooler clip in the way
maybe if i carefully bend the caps.. 😬
a bit of terrifying capacitor wiggling did the trick indeed
this board is honestly a masterclass in the awkward placement of things
but its fine. i am ready to try powering on
ITS HAPPENING
apologies for the IDE terminology
ok then i need to think about storage. this thing does appear to have SATA. not sure if it can boot from USB for installation purposes
i made a FreeDOS FullUSB drive but will continue after dinner and sauna
USB boot is real
(short detour to unfuck power settings on my laptop to make it charge again)
well, i can boot into FreeDOS on the USB drive but it doesnt seem to see the SATA HDD at all
maybe i will just install XP since i know my way around that

well, booting XP installer from USB turns out to be harder than even OS 9. pondering whether burning a CD or installing to the HDD via a VM would be less annoying

also i am starting to want a PicoIDE

partner fell asleep so i gotta quietly move this stuff out of the living room 😄
for the VM route i guess i first need a SATA AHCI driver for the controller VirtualBox emulates and then another one post installation for the actual mobo. urgh
now making an ISO containing ICH8M driver using nLite...
"Don't contact Microsoft for troubleshooting nLited installations" dont tell me what to do!!
yes hello john microsoft. kindly fix my XP installation
man Disk Management sucks (on Windows 10)
progress!

wow theres installation music? i dont think ive ever had working audio at this point before

i believe i have the correct driver installed now but the Athlon machine will not boot from the SATA drive

fine. i will try IDE

Your computer will be faster and more reliable
VM-installed XP on an IDE drive gets a bit further, to the "Windows failed to start up" screen where it offers safe mode and such. but no luck from there, safe mode or not

i remember making a pretty non-annoying xp install usb once

and once again, don't ask me how. (the produced usb was reformatted, so i can't even go to look for artefacts.)

@ozzelot i feel like ive done it too but the last time i ran XP was on a mac which is a whole other can of worms
@ahihi have you considered getting a compact flash card? They're pin compatible with IDE and you can image it on another more modern machine to save some hassle with usb boot etc?
@bridge yes, but i want the SATA bandwidth if i can get it
@ahihi IDE 133 vs sata 1 is 17mbs extra bandwidth for sata, and you might have issues on FreeDOS with sata? I've never used freedos but I imagine IDE is likely better supported
@ahihi My thoughts are twofold:
-is the SATA controller doing AHCI, and if so, does FreeDOS support AHCI?
-is the SATA controller doing some bespoke RAID stuff that would need proprietary drivers?
@ahihi Within that framing, I feel you would run into the same problems with XP.
@ahihi (You could inject drivers right into your XP installer (aside from putting them on a floppy), but you will need to know what you need. And I don't remember how to do it anymore.)
@ahihi I'm looking into the manual (from https://theretroweb.com/motherboards/s/abit-ab-kv-80 ) and from what I can understand, the SATA controller here can only actually be bootable if the RAID ROM is enabled. And I don't know how keen DOS is on that. You might be best off getting an adapter to IDE.

@ozzelot i have various IDE drives too so this is fine
@ahihi
In that era, I should hope so... but I would perhaps hope falsely.
