I also tried with a controller . It has been sitting like this for at least 5 minutes sometimes. POST card displays --, it does not show POST codes at all on this board. I am going to try another PSU this evening, swap the RAM and also checking some traces near the keyboard connector. Not really …

No Post Code? Tried another Slot? Any beep Code?

No Post Code? Tried another Slot? Any beep Code? I think it actually completes POST. Beep codes are normal. I will cycle through the POST codes on the POST card this evening. On a cold start, it stops at the WAIT.... as seen on the picture. I can then reboot it using CTRL-ALT-DEL (so it's not …

No POST codes shouldn't happen on this mobo - perhaps you have one of the address or data bit lines busted, that would also explain the hang. But do check if your test card is not set to XT class system (I haven't seen a modern ISA/PCI test card capable of that though). Try booting without any …

Well at least there's that. I'd still check all the ISA address lines, all those should be connected to one of the big chips.

Well, since the kid was sleeping I could do a visual check of the board. No visible damage. I also reseated all socketed chips and reflowed some of the worse looking solder connections (esp. keyboard and in the battery corrosion area).

Visual inspection might not be enough. Use this pinout: https://upload.wikimedia.org/wikipedia/commons/9/9f/ISA_Bus_pins.svg Check all address lines (but above all A0-A11 on the 8-bit slot part) with a meter set to beep on continuity. All of them must be connected to the same big chip, it's not …

Nah, if you can't find any connection at all then the chips are using the '244, '245 and '373 (which your board has plenty of) as buffers/latches and that complicates things. You're unlikely to debug that with just a meter at your disposal. There is some battery corrosion though so check this area …

If your board is a C2 revision then you can use EDO(not all later revisions allow EDO though - F does not for example). Just stick in the ram into an old 486 board which features 72 pin simms - if it starts up the ram is FPM. Another option is reading the numeric code on the modules - if it ends …
