Plug & Play does not appear to be implemented in under dsl-3.4.7 (Edit: or dsl-4.x):| Code Sample |
lspnp
lspnp: /proc/bus/pnp not available
$ ls -l /KNOPPIX/sbin/lspnp
-rwxr-xr-x 1 root root 10860 Jun 25 2005 /KNOPPIX/sbin/lspnp
$ ls -l /KNOPPIX/sbin/setpnp
-rwxr-xr-x 1 root root 5976 Jun 25 2005 /KNOPPIX/sbin/setpnp |
- if this is the case 16KB could be saved but it is probably better to check on other hardware first...
Note that under dsln-rc4 on the same machine, pnp is implemented albeit in a different place:| Code Sample |
$ grep -i 'smc' /sys/bus/pnp/devices/*/id
/sys/bus/pnp/devices/00:0c/id:SMCf010
$ cat /sys/bus/pnp/devices/00:0c/resources
state = active
io 0x2f8-0x2ff
io 0x280-0x287
irq 3
dma 3 |

If it makes sense, I'd like to suggest that lspnp/setpnp in dsl are replaced by scanport from the Debian hwtools package.
Example output:| Code Sample |
$ sudo /sbin/scanport

I have gotten seg faults and system hangs on my various old hardware. I don't think I can include scanports in the iso.
Will delete unused lspnp & setpnp.

- OK, that's understandable. I'll leave scanports in the irda-utils extension since irda ports seem to be one of the hardest things to find.
