Some pictures of the motherboard:
[Back]
[Jumpers one and two. Also proof that Bank 1 is the one closest to the edge of the mobo]
[Front overview]
[Close-up of the upper jumpers]
[RAM sockets. No funny business here, it seems]
EDIT: After re-installing the motherboard into the case and booting it up, HIMEM.SYS/A20 now miraculously works.
I don't know what I did or how I did it, but thanks to everyone who followed me on this weird journey.
