ZZZzzz…) +<GNUtoo-irssi> x60 and x60t +<GNUtoo-irssi> oops +<GNUtoo-irssi> x60t and t60 +<GNUtoo-irssi> I'll test them together, I was trying lirc instead directlyt +<phcoder-1creen> 5242 for X60 +<GNUtoo-irssi> ok +<GNUtoo-irssi> thanks +<phcoder-1creen> GNUtoo-irssi: did you see x200 port? +<GNUtoo-irssi> yes +<GNUtoo-irssi> what CPU is it? +<GNUtoo-irssi> and what chipset? +<phcoder-1creen> gm45. Intel GPU +<GNUtoo-irssi> ok +<GNUtoo-irssi> I've looked at your new ports and related, +<GNUtoo-irssi> it probably cover the chipset I have in my N71JQ +<GNUtoo-irssi> but I probably don't have time to do the port anytime soon +<phcoder-1creen> gm45 was already covered by rk9 +<GNUtoo-irssi> yes +<GNUtoo-irssi> it's core 2 duo with the first AMT in the NICs, right? +<GNUtoo-irssi> and 64bit? +<phcoder-1creen> it's 64bit. I can't tell anything about AMT. +<GNUtoo-irssi> so I guess that if someone unsolder his nic firmware flash, the AMT is gone? +<GNUtoo-irssi> ok +<GNUtoo-irssi> if so that's probably a good tradeoff +<GNUtoo-irssi> you get more recent laptops at the cost of unsoldering or blanking the NIC's flash +<phcoder-1creen> ME firmware is in the flash chip. There is information that on gm45 you can remove ME firmware without any consequences but I din't really try +<GNUtoo-irssi> assuming it's like with the old i945 laptops +<GNUtoo-irssi> ok, wow, nice +<GNUtoo-irssi> how fast is it in between the T60's and the Nehalem's laptops(x201) +<phcoder-1creen> roda rk9 runs without ME firmware AFACIT +<GNUtoo-irssi> ok +<GNUtoo-irssi> about roda and so on, there isn't a lot of infos on the rugged laptops +<GNUtoo-irssi> I guess that nobody still test on them +<phcoder-1creen> No. But the list of connectors they have is truly impressive. As is battery capacity and heaviness. +<GNUtoo-irssi> indeed +<GNUtoo-irssi> it probably has lot of interesting peripherals too, like GPS, 3g modem(how is it connected?) and so on +<GNUtoo-irssi> for the heavyness, it's a way to make geeks become like rambo? +<GNUtoo-irssi> s/geeks/geeks and nerds +<phcoder-1creen> 3g modems are optional. I guess it's minipcie slot. +<phcoder-1creen> BTW x200 has 3 minipcie slots +<GNUtoo-irssi> wow +<phcoder-1creen> (not counting exprecsscard) +<GNUtoo-irssi> ok +<GNUtoo-irssi> that permits to have 2 wifi cards... +<phcoder-1creen> if driver can handle it, sure. When I tried with 2 intel cards, intel drivers and networkmanager got confused. +<GNUtoo-irssi> (ath9k/ath5k have some difficulties when creating multiples interfaces when WPA is involved) +<GNUtoo-irssi> ok +<phcoder-1creen> 3rd minipcie was intended for UWB. +<GNUtoo-irssi> well, I have multiples cards easily here +<GNUtoo-irssi> I never had a problem with non-intel cards +<phcoder-1creen> network manager will still get confused +<GNUtoo-irssi> example: ath9k + ath9k_htc => both interfaces appear in kde's network manager GUI +<GNUtoo-irssi> it was getting confused with intel cards and rfkill +<GNUtoo-irssi> (and I lacked the fimrware of the intel cards...so that added to the confusion) +<GNUtoo-irssi> Example use case: connect to 2 different AP on 2 different networks +<phcoder-1creen> yes network manager and multiple cards and rfkill resultsin confusion +<GNUtoo-irssi> my ath9k_htc is usb +<GNUtoo-irssi> so no hardware rfkill +<GNUtoo-irssi> btw, the mini-pcie connectors do export only pci? +<GNUtoo-irssi> do they export usb, and sata? +<GNUtoo-irssi> (and some other pins for rfkill, SIM card, and so on) + + + + + + + +<GNUtoo-irssi> ok +<GNUtoo-irssi> well, I must update the instructions +<GNUtoo-irssi> I was going trough the list of patches I had first +<GNUtoo-irssi> yes +<GNUtoo-irssi> but to a specific/personal page +<vimuser> could you link me to the updated instructions? (when done) +<GNUtoo-irssi> well, I'll update them first +<GNUtoo-irssi> I was going trough my patches list before that +<GNUtoo-irssi> so I'll do that now +<vimuser> So I gather that you basically reset the counter yourself after you boot (after typing grub password) +<vimuser> and so, if you boot and the counter is higher, you know if someone tried to use it +<GNUtoo-irssi> yes, my systemd unit does it +<GNUtoo-irssi> *resets it +<GNUtoo-irssi> so it works like that: +<GNUtoo-irssi> the bootblock switch from normal/ to fallback if the counter is > CONFIG_MAX_REBOOT_CNT +<GNUtoo-irssi> if no normal/ is there it also switch to fallback/ +<GNUtoo-irssi> and then it increments the counter +<GNUtoo-irssi> (it's badly explained by me but you get the idea) +<GNUtoo-irssi> then my systemd units reset the counter to 0 once it's fully booted +<GNUtoo-irssi> that way if it fails, let's say at booting any linux kernel, then the user won't have bricked the laptop +<GNUtoo-irssi> (and the developer will have saved lot of time) +<GNUtoo-irssi> the issue is that I didn't reset the counter at resume +<GNUtoo-irssi> I should look how +<GNUtoo-irssi> but at least that makes it developer friendly if the user don't have suspend-resume covered yet +<GNUtoo-irssi> testing images is then a lot faster +<GNUtoo-irssi> and for "production", only fallback/ populated, but with the mecanism in place +<GNUtoo-irssi> that way he can test normal/ easily + + + + + |
