Installing Debian/Linux on Thinkpad Edge E320 Core i5

Got the new family member. Okay, eventually it was unavoidable that after being computer and network engineer for 20 years I going to buy a laptop. :-P So far I survived with desktop machines (and you know they accumulate pretty nicely), mobile phones (obviously Android, but they're way too small for real work) but now I realised it cannot go on anymore. I've been on the way for days and often I had to fix things and it's just not possibe using that phone...
I've been fighting this for 2 years now. The old Thinkpad T40 I inherited completely died, first the video ram got funnies, then the fan then the cpu went to see the Great Manitou. The next problem was to find something cheap without being sucky-sucky. I realised that if I want to have the best possible solution it'll take about forever. So okay, let's see what is NOW available around. This one is probably old enough to be cheap (as far as I see it's not listed in the current model line anymore) but good enough to be useable. Originally it's been a Toshiba but Lenovo got a more powerful cpu and better features.

Finally I picked a Lenovo Thinkpad Edge E320 129888G, Core i5-2450M @ 2.4GHz, 4G RAM, 320GB (290GiB) hdd and an Intel integrated and an ATI Whistler video card with a Radeon 6600M chipset. It possess a b/g/n wifi (Intel), an SM card reader (RTS5116 from RealTek), DSub and HDMI for ext video and an E-Sata for, well, just because. And 2 usb and the gig ethernet from Atheros closes the line. Not that bad, overall, for 3-6 hours of battery power. I mean, for approx $730 or €545.

Okay, that wasn't what I wanted to talk you about. I wanted to talk about:

Installing Linux on E320

It sucks. No, really, it does suck pretty hard. I mean, I'm doing this shit for 25+ years now and still took me the better half of the day, and a bit of the next. With the help of experience, google and lots of patience. And it's not Linux who's to blame, mind you.

Okay, so this came preloaded with some windows trash, v0.7 or something, for the fun without any install media. Which means that if it gets screwed up then you're probably on your own. Brilliant. Oh, I mean, no problem, windows never gets broken.

So this machine starts up nicely apart from the microsoft trash on it. I remembered that ages ago I've used Partition Magic to shrink it, but it seems it doesn't really exist anymore. But google told me that this kind of windoze can actually do it by itself. Really, it has the disk utility built-in which can actually - amond other things - shrink the partition. And worked pretty well, for a windows program.

So I have shrunk it to ~48 Gigs and the rest to be used. The disk contain 3(!!) partitions, one for thinkpad stuff and other is for some windows driver crap or whatnot, but fortunately one left to be used for logical partitions. (Don't get me started on EFI, that comes soon.)

So there's the partition, let's install it. I have a DVD install but I have no DVD in the machine, but fortunately I have an external USB drive. So lets boot!

Um, it doesn't. Starts windows (and every time either you wait for the crap to finish or have to poweroff it since there ain't to reset buttons on mobile stuff), everytime.

Okay, let's change the BIOS settings. I mean... I ... wtf? No bios prompt at boot. "Press ENTER to abort booting." Very funny fsckers, it goes faster into the bloody windows again.

Let's see F1? No. Ctrl-whatever? F12? Looks weird but no. Okay, the net told me F2, but F12 could be good for it either. So F2, enter the BIOS, and activate that bloody "show enter bios prompt" setting, and move over to boot order.

Boot order looks fine: first usb stick, then cd, then whatever, last hdd. Still, doesn't really care about it, starts hdd everytime.

Here came a longer gap when I have tried to look up what UEFI and EFI is, why and why not, what and whatnot, since this beast supports EFI boot. If you wonder you can look it up in Wikipedia.

No luck. Latest Debian DVD is supposed to boot on EFI as well as USB stick images, but no. I can set EFI only, no. I have tried Legacy Only and no. It may have been related to the fact that the machine boots faster than the DVD can identify the media. So I have disabled the hdd from boot and this way it was a bit faster to figure it out, without the need to see windows anymore.

Well, some combination of EFI and legacy boot, with efi first if I remember correctly, plus using the F12 boot which was able to delay the booting I was able to start the DVD. (After the mess I figured that newest USB images, which contain everything including the MBR can boot as well, but no way if I try to use my own MBR.)

The install went well, from an older Debian x64, installed grub, and I was kind of realised it won't be that simple.

And it wasn't. Grub didn't boot at all, no operating system. The fscking lame BIOS is made for windoze and if some windoze shit isn't there it thinks there isn't an OS around. No matter MBR signature is ok, the partition table is ok... something is required which isn't just there.

Another bunch of hours passed with several moves of trying to get an EFI boot, no luck, or to try to figure out some combination of partition table which works, without much success. In the meantime I was able to find an USB stick state which was able to boot, containing a new (v1.97) GRUB and the partition table created by grub-mkrescue. So I figured upgrading Debian to latest (sid) may help, because it contains the new GRUB plus it may support EFI, too.

Upgrading obviously requires a working ethernet or wifi, and obviously... none of them were detected. For the record, here are the internals:

09:00.0 Ethernet controller [0200]: Atheros Communications Inc. AR8151 v2.0 Gigabit Ethernet [1969:1083] (rev c0)
So, we have a Centrino Wireless-N 1000, which requires iwlwifi driver and more importantly its firmware images which isn't quite free, so it goes onto the USB stick, into its root specifically. The installer requires to look for missing formware images on external drives, finds the usb and uses it nicely. Still, wifi setup isn't trivial in the installer (especially when using WPA2).

The ethernet... well it's an atheros 8151, using the atl1c driver, which is part of debian, and doesn't even require any external firmware... except it just doesn't get detected.

A nice summary can be read on the Debian wiki which tells the secret:
echo "1969 1083" > /sys/bus/pci/drivers/atl1c/new_id
And after that udev finds the card nicely. A small problem is that when you have to try to reboot many times (to fix the aforementioned boot issues as well as others) this has to typed every time. Bummer, no mouse on console while installing.

Well yes, the upgrade worked, but still no boot. Dammit.

Another round of fiddling started, which resulted a working combination of BIOS (efi then legacy), and MBR (GRUB's code but windoze partition was set as boot media!) and a few twists with encrypted swap (which changed UUID in the meantime and update-initramfs completely screwed up figuring it, so /etc/crypttab had to be edited then initrd had to be completely removed and re-created), and after all I ended up with a working multibooting Debian.

As a closing act I wondered whether windoze 0.7 survived, as people mentioned for windoze 6? xp? whatever? that it dies when MBR changes and require a reinstall media to fix, which I obviously didn't possess (this was the reason for the honorable mention in the first paragraph). Lenovo rescue was beyond rescue: bad media, fix me with the DVD, but what DVD nobody could tell. To my greatest surprise years didn't passed vainly on windoze as this extreme professional version choked on MBR change (but of course, what else to do anyway), but offered to fix itself and lo! it just did. So I have a windoze partition as well as a game console or for those programs which exist only there.

It wasn't that hard. ;-)

Right now Everything Works™, even the SD card reader. I have tested with dual monitors and it works nicely. I didn't test eSata but everything else looks fine. Battery time is 3hrs with active use or close to infinity when suspended, real life lies between these two, my guess would be around 4-5 hours. Charger is pretty quick: fully charges around 1 hour.

So far I'm happy.
