A lifetime ago, I was on the support desk for a 5250 emulation company (BlueLynx or Micro Integration). The company is long gone, but the products I supported were direct rivals to IBM's (mainly because they were difficult to use). But I digress.

If I recall (and I often don't) on those OLD x86 machines you had to go into the BIOS and reserve blocks of memory that those cards used.

As I *know* from relatively fresh experience, it's not about reservation but if certain segments may be cached (in L1/L2 cache) or not: Some software behaved erratically if cached. Others ran a lot faster when compatible and cached. Where (start address) and how much (window size) of that memory said memory area is used, is configured on the cards individually.

I'm also fairly sure that IPX/SPX (Netware) often conflicted with the Token Ring communications.

I guess that could be the case. But when testing, I didn't start the Netware Client. So the adapter was definitely free.

But I think that's why our twinax gateways were so popular... they ran on NetBIOS, IPX/SPX, and (gulp) Banyan Vines natively.

I'm missing AppleTalk. ;-)

OMG - I think I just got a pimple :).
