Much better images and, unfortunately, confirms what my eyes were seeing ~ if you care, DO NOT power this board up again ~ it needs repair/revamp/reworking first... ...green crusties in the keyboard IC socket gave it away... all of that area will need redressing (new IC socket, check all components …

Is it me or does that board look more like a 286 or 386sx perhaps? I don't think I've ever seen a 486 with a high/low bios and a socketed PLCC chip like that. It's such a poor image it's hard to say .... to me it looks like varta damage everywhere... Is this a better image? https://imgur.com/ …

ok good to know. I will try to figure out how to install that and try the boot process again.

another note its that the keyboard controller chip is not installed. does that matter? I have the chip but when I purchased from Ebay, the seller told me it was not installed but was included in the package. not sure where to install that either

The card that is in there now seems to …

@Datadrainer and @PCHoaderPatrol, thank you for your help. Its working now, even set the CPU jumper to 33MHz instead of 25Mhz
