Now that we're back from the gym, and I'm not feeling much like moving from the computer, I should tell the world what we've been up to lately.

Tonight, the gym, for the first time in four weeks for me, somewhat longer for [livejournal.com profile] rwrylsin - and it certainly felt like it. I've lost quite a bit of fitness, and probably some strength too (I was around 82-83kg before the recent chest infection; 78kg just after; and back up to 80kg now after having appetite again for 10 days or so). Fortunately, there's some time before the next fencing competition to get back in shape (again). It is getting quite annoying spending so much time either sick or recovering, though.

Yesterday, a quiet day, with a brief shopping expedition. Also a spot of computer upgrading, which I will write about in a separate post.

Saturday, a trip to Edinburgh[1]. First stop was shopping on Princes St, with a stop in Jenners to look at cookware and Lego (both conveniently located in the basement), and in a tourist shop to see if there was anything interesting. Nothing really grabbed us (well, maybe a little Lego :-) ), and we moved on.
On, to Craigmillar castle. We've been there twice before, both times after a [livejournal.com profile] live_jnl_north meet, and the first time we only arrived 30 minutes before closing time, and the second time we got there after closing time. This time we were determined to see the whole place, and now that they're on summer opening hours, we managed it.
Craigmillar is an interesting place, not least because it's been reworked and remodeled so many times. As [livejournal.com profile] rwrylsin wrote , it's a rather confusing place, too, and we didn't quite understand why some things were done (e.g. blocking up various windows and doorways). Finally, we were done, and we'd seen most of the nooks and crannies, and headed on home and collapsed in front of the TV.

Now, I just have to hope that the support mobile for work doesn't ring tonight (or any time in the next week or so), and catch up on some sleep.

We're going to Prague ! In less than two weeks !! Can you tell that I'm excited ?!

([livejournal.com profile] rwyrlsin, in a fit of feeling-much-better-after-the-recent-illness, started thinking about things to do on the upcoming long weekend. Obviously, we could go touring around Scotland, or perhaps pop down to London, or visit some other bit of the UK. Then she broadened her horizons, found some cheap airfare/accomodation packages, and wheee ! We're off to Prague (Praha), and we don't speak a word of Czech (čeština), but we have a little phrasebook now. Whee !)

Every now and then, I get stuck on a problem, and start Googling around to find some sort of solution or hint to get me moving again, and end up finding a previous newsgroup, mailing list or forum post made by ... me ! Usually finding this is sufficient to either give me the solution to my problem, or jog my memory about how I had previously solved it, or at least give me hints to push me in the right direction (again). Pity my memory isn't better ...

Anyway, I had a couple of problems with my little hardware upgrade on Sunday night and tonight, so I'm documenting it all here, so if I come Googling in the future, I will find the answers I need.

The hardware part of the upgrade was fairly simple - add 512Mb to give 1Gb in total, and add a sound card (rather than using on-board sound). The physical part of it went smoothly, then I put the case together and booted up into Linux - where I found that I couldn't see all of the memory, only about 900Mb.
I found the following errors in system logs :
Warning only 896MB will be used.
Use a HIGHMEM enabled kernel.


Googling followed, and I realised that I needed to either recompile my kernel to enable that option (couldn't be bothered, since it was 10pm-ish, and I was meant to be in bed by then to get up at 6am today), or download a suitable kernel rpm and install it, which is what I did (urpmi is my friend).
Unfortunately, after running /sbin/lilo , then rebooting, I now had three problems :
1. The new kernel didn't show up as an option in the Lilo boot menu.
2. I couldn't start X Windows.
3. I still couldn't see all 1Gb.

I spent some time Googling and trying to figure out what was wrong. I eventually worked out that installing a new kernel had overwritten or otherwise incapacitated the special NVidia drivers my video card requires, so downloaded the latest drivers and installed them, and lo, X Windows was working again. Since it was getting late, I quickly checked LJ and various web comics, then headed for bed (around 12:30am, oops !).

While lying there not quite drifting off to sleep, I finally realised why the boot menu wasn't updating. It is related to the way I have set up dual-booting with Windows and Linux. I have two disks, and the first one has Windows. I didn't want to backup that disk, repartition to allow a Linux boot partition, then reinstall Windows on it, so I used the Windows boot menu instead. This involved adding a line like 'c:\bootsect.lnx="Linux"' to c:\boot.ini , and creating the bootsect.lnx file by copying the first 512 bytes of the disk that Lilo is writing its boot record to into a file (e.g. dd if=/dev/hdf bs=512 count=1 of=bootsect.lnx in my case). This works fine ... but I had forgotten to update the bootsect.lnx file after upgrading my kernel and running /sbin/lilo, and thus the failure of the boot menu to update, and the failure of the updated kernel to run, were explained.

This evening, I copied the boot sector across, took some time out to install drivers for the new sound card in Windows, and then rebooted to Linux to find that I did indeed have the new kernel in the boot menu, and it was running, and my 1Gb was available again. Whew. Of course, now that the new kernel was running correctly, I'd somehow lost the NVidia drivers again , and for some reason, didn't have the installer that I used last night lying around, so had to download it again (manually, this time), and then reinstall.

Finally, though, everything is working again, memory and sound card and all. Whew.

(meanwhile, I had to retype this after Firefox seg-faulted, darnit)
