PNPDUMP(8)

NAME
pnpdump - Dump ISA Plug-And-Play devices resource information

SYNOPSIS
pnpdump [ devs readport ]

DESCRIPTION
pnpdump will scan all the ISA PnP cards, dumping their resource data to stdout. The output is in a form that can be used by isapnp, except that the actual configuration statements are commented out. See isapnp.conf(5) for details of the format. By default, pnpdump will reset all the cards into the inactive state, then ISOLATE each one and allocate it a handle (Card Select Number). Resetting the cards may be undesireable, in which case two additional parameters may be supplied:

  Parameters

devs
    is the number of PnP cards that the BIOS has found, ISOLATEd and allocated CSNs to in the system. Note that if this is greater than the actual number of cards in the system, pnpdump will stop scanning when it receives a first serial identifier byte of 0xff (this is what happens when there isn't a card with that CSN).

readport
    is the address of the readport to use for the Plug-And-Play access. The number base is determined by the format: a leading 0x implies hex, a leading 0 implies octal, otherwise decimal is assumed. The address of the readport must be chosen to avoid any conflicts with existing (non Plug and Play) hardware, and must be in the range 0x203..0x3ff.

Note that for these two parameters to work, you must have a PnP BIOS which has already carried out the ISOLATION process correctly.

FILES

/sbin/pnpdump
    The executable.

/etc/isapnp.conf
    The resting place of the editted output.

BUGS
None known about. If you think you have found one, please send a report to isapnp@roestock.demon.co.uk.

WARNING
This program can reset all your Plug-and-Play devices. Use at your own risk.
