Hi !
I need an help about a card I found in the 5363.
There's only a P/N, 92X7245.
A quick search on ebay gave poor results: IOP card.
It looked like a processor card: infact I found, under a heatsink, an
80286, 512MB of ram, ROM BIOS ...
Under OS/400, an IOP card is related to an embedded server, but under
SSP ?
It has only a DB-9 female connector, like a CGA or MDA video adapter,
but no provision for keyboard.
Any hint?

Sounds to me like something like the cards you could get for the early
Macs, and even the Amiga. which was basically a single board PC that would
let you run your DOS applications on your non-PC workstation. I'm guessing
with this one that you hook up the external monitor for it and an
application would let you switch over and use the host keyboard for the
card. I'll see if I can find if that's the case for this card.
PS: Are you sure it's 512MB and not 512KB? I don't think I've seen 286
address that much RAM.

Yeah, it was a typo ! Obviously it has 512KB, not MB ;)
It's definitely a processor card. A 286, RTC, chipset Faraday FE300, DMA
controller, two 8259, AT-BIOS Faraday (just dumped with the eprom
programmer)
FE-AT BIOS, COPYRIGHT (C) FARADAY ELECTRONICS 1/1/1985...BUS-AT Ver
1.1i RLM
I don't see it with CNFGSSP, must dig better...

"Normal" 286 (and 386-SX) could address 16M.
386-DX and above could handle more.
"REAL" mode could address up to 1M with 20 address bits, and up to 1M plus
655220 bytes of memory, with A20 support.
Memory past 1M was called "Extended" (XMS).
It was, at least theoretically, possible to go past 16M with "Expanded"
memory (EMS) What was the max for the LIM (Lotus-Intel-Microsoft) EMS
standard?

You could only address 65520 additional bytes in realmode by ungating A20 on a 286/386
which I assume is what you meant - just a typo

I believe that for LIM 4.0 in MS-DOS 7.10 (Windows 98) it's 32MB. At
least that's what emm386.exe reports at load time on a box with 2GB RAM.
That's running just the extracted DOS environment, loading himem.sys
and emm386.exe. I just had occasion to fiddle with it last week.
