I suggest you look at the %windir%\inf\pnports.inf file and in

A multiport is simpler than implementing 12 PCI functions in FPGA
(though our engineers say that isn’t very hard) and also easier to install.
But that’s is the gotcha… Seems that I gave a bad advice to the OP:
all in-box MultiportSerial drivers in XP are either not PCI - or have
custom drivers. I don’t understand why serial.sys could not handle at
least “plain serial” cards.
The goal is to avoid writing a driver (except maybe an INF, that refers
to in-box serial.sys).

If you want to use the inbox support (SERIAL.SYS) then you must conform
to its expected model for multiport serial devices. If you do this, you
may not need an INF at all.Good Luck,
