I believe the card I am using is a Rosewell. It was about a $20 bill mail
order. As for finding it, here is the lspci -vv output, snipped down to
that card:
00:0a.0 Communication controller: NetMos Technology PCI 9815 Multi-I/O
Controller (rev 01)
Subsystem: LSI Logic / Symbios Logic Device 0020
Control: I/O+ Mem+ BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr-
Stepping- SERR- FastB2B- DisINTx-
Status: Cap- 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort-
<TAbort- <MAbort- >SERR- <PERR- INTx-
Interrupt: pin A routed to IRQ 11
Region 0: I/O ports at a000 [size=8]
Region 1: I/O ports at a400 [size=8]
Region 2: I/O ports at a800 [size=8]
Region 3: I/O ports at ac00 [size=8]
Region 4: I/O ports at b000 [size=8]
Region 5: I/O ports at b400 [size=16]
Kernel driver in use: parport_pc
Kernel modules: parport_pc
and I believe I am using the $A000 address.
However, on inspection of my .hal files, I see I am still using the
motherboards port at the usual 0x378 address. The plans of mice and men.
;) I do have plans (only) for a mister control signal and a few other
items to be added to my own lashup in due time.
And worthy of note, that motherboard parport does not show up in the lspci
listing. Could be a quirk of that motherboard I suppose, and I just never
noted it was missing before. It is adjustable in the BIOS though.
