peek and poke an isa device
|

| John Price 2002-08-28, 6:29 pm |
| I would like to write a user application that would be capable of peeking
and poking I/O devices. Particularly ones on an isa bus(specifically
registers on a given isa device).
Is there a system call I can make that would give me a base address that I
can use to start looking for isa devices?
thanks
John

$ man -k isapnp
isapnp (8) - Configure ISA Plug-and-Play devices.
isapnp.conf (5) - File format used by isapnp
You could take a look at the source, how this progs work.
Good luck

Quaere:
Were these devices not detected on boot by "isapnp" and shown in dmesg?
