- - Why is my PnP card not found (or found as - unknown)? - - - - The reasons for this behavior are explained by the - following email, posted to the &a.questions; by &a.peter;, in - answer to a question about an internal modem that was no - longer found after an upgrade to - &os; 4.X (the comments in - [] have been added to clarify the - context). - - - The contents of this quotation has been updated from - its original text. - - -
- The PNP bios preconfigured it [the modem] and left it - laying around in port space, so [in - 3.X] the old-style ISA probes - found it there. - - Under 4.0, the ISA code is much more PnP-centric. It - was possible [in 3.X] for an ISA - probe to find a stray device and then for - the PNP device ID to match and then fail due to resource - conflicts. So, it disables the programmable cards first - so this double probing cannot happen. It also means that - it needs to know the PnP IDs for supported PnP hardware. - Making this more user tweakable is on the TODO - list. -
- - To get the device working again requires finding its PnP - ID and adding it to the list that the ISA probes use to - identify PnP devices. This is obtained using - &man.pnpinfo.8; to probe the device, for example this is the - output from &man.pnpinfo.8; for an internal modem: - - &prompt.root; pnpinfo -Checking for Plug-n-Play devices... - -Card assigned CSN #1 -Vendor ID PMC2430 (0x3024a341), Serial Number 0xffffffff -PnP Version 1.0, Vendor Version 0 -Device Description: Pace 56 Voice Internal Plug & Play Modem - -Logical Device ID: PMC2430 0x3024a341 #0 - Device supports I/O Range Check -TAG Start DF - I/O Range 0x3f8 .. 0x3f8, alignment 0x8, len 0x8 - [16-bit addr] - IRQ: 4 - only one type (true/edge) - - [more TAG lines elided] - - TAG End DF -End Tag - -Successfully got 31 resources, 1 logical fdevs --- card select # 0x0001 - -CSN PMC2430 (0x3024a341), Serial Number 0xffffffff - -Logical device #0 -IO: 0x03e8 0x03e8 0x03e8 0x03e8 0x03e8 0x03e8 0x03e8 0x03e8 -IRQ 5 0 -DMA 4 0 -IO range check 0x00 activate 0x01 - - The information you require is in the Vendor - ID line at the start of the output.
