	+	The photo is '''really hard''' to make sense of and thus doesn't really add anything to the page. Maybe it needs some processing to have a much higher dynamic range (so that one can differentiate the IrDA black window from the ThinkPad's black frame), or it should be a more distant photo of the thinkpad's side/front with the IrDA window circled in red?

−	~~The "wrong chip version ff" is a real issue, and having it mentioned makes sure that google searches turn it up with a solution.~~

−	~~----~~
−	The present text confused me (as you now have noticed). Maybe it should better reflect that the error is incorrect ("wrong chip version ff" instead of "FIR mode not enabled" or whatever). Would that be acceptable?

−	~~----~~
−	~~If you think you can explain it better, go right ahead. The IrDA document could use some major cleaning.~~
−
−	As long as we still point out that the only error in syslog is "Wrong chip version ff" when trying to load the FIR module without first activating the PnP device. It would be nice if the ISA-PNP patch to the nsc-ircc driver got accepted upstream, so we dont have to do these hacks anymore.

−	~~Is there a reason why you deleted the TODO entry for linux 2.6 kernel config for SIR? I would like to readd it, but like to hear your reason to remove it first.~~

−	~~== T23 debianized kernel with probs ==~~
−
−	Found another crazy thing here. T23 2648-2GG, with 2.6.13 and 2.6.14 (Debianized Source). Clear init of nsc-ircc and dongle, but the dongle stays offline (dark and blind). Booted with Knoppix or Bart-PE Windows give correct function of the whole device, viewed with a digicam shows some blinks at init. But not with plain 2.6.13 an 2.6.14 from Debian.
−	~~Eric~~
−
−	~~== setpnp ==~~
−
−	~~Hello,~~
−
−	since the nsc-ircc patch isn't in 2.6.15, I tried to go the setpnp route, but I don't even get to see {{path\|/proc/bus/pnp}} even though I enabled the support for it in the kernel config (once I found out that I need to enable ISA support to even get the option). Has anyone successfully used setpnp to enable the IRDA port or is that just some sort of urban legend? ;)
−
−	~~--[[User:Spiney\|spiney]] 19:12, 4 Jan 2006 (CET)~~
−	~~----~~
−
−	~~Make sure you enable pnp-bios support specifically when compiling the kernel, just enabling pnp support is not enough.~~
−	~~I must however admit that I have not done this, since my ancient TP 770 running a 2.4 kernel, which was at least 5 years ago.~~
−
−	I just looked at a 2.6 menuconfig myself, and could not find the option, but looking at my .config file I can see the CONFIG_PNPBIOS option, so you might just want to edit the config file directly, enable the PNPBIOS option, and run make oldconfig.
−
−	~~--[[User:Tonko\|Tonko]] 19:38, 4 Jan 2006 (CET)~~
−	~~----~~
−
−	I do have the pnp-bios support enabled (the option is depending on ISA among others, checked the Kconfig file in the source tree to find it), and also the proc-Interface option, but still no go... maybe it's not compatible with CONFIG_PNPACPI? Oh well, nevermind, going back to the patch, that works with less hassles, I just hope it'll end up in the vanilla kernel eventually. Still thanks for the help.
−
−	~~--[[User:Spiney\|spiney]] 20:22, 4 Jan 2006 (CET)~~
−	~~----~~
−
−	Ok, on further investigation (not giving up that easily ;) it really seems that CONFIG_PNPACPI is disabling PnPBIOS, at least dmesg showed something along the lines of "PnPBIOS: disabled by PnPACPI". But, after recompiling without PnPACPI, I still can't get it to work. I can use {{cmd\|setpnp\|}} and {{cmd\|lspnp\|}} just fine, but the nsc-ircc module won't load:

−	~~----~~
−	~~No idea what might be wrong, perhaps it does not work on more recent machines, or kernels.~~

−
−	BTW, is it just me or does the nsc-ircc patch only work if CONFIG_PNPACPI is set in the kernel config? Otherwise the module loads fine, (but without stating in the kernel log that it found the dongle) and using IRDA does not work, irattach returns "irattach: ioctl(SIOCGIFFLAGS): No such device".
