LHAVEN is dead, long live LHAVEN?

Well, I was getting really annoyed with it complaining and kicking out the replaced disk in LHAVEN. So, I shutdown the system and took out the disk, figuring it should just continue to run fine degraded until I get around to replacing it.

Well, it wouldn't power on after that. I went through everything, no joy. It had done this a while back when I tried adding something to it. It could just be the power supply has flaked out, but I don't have a tester or multimeter handy...so I can't really test it. Could buy a new PS...and I may do that.

But, I kind of suspected the drive issues weren't actually the drive but possibly some deeper hardware problem. So, I had been planning to replace LHAVEN at some point. It has done quite well, being circa 2002. Started out as a 64MB Duron 800MHz machine, eventually peaked at 2GB Athlon XP 3000+. It had replaced a Cyrix PR233 box that had gone up in smoke during a hot summer day in 2002, when the transformer outside blew....the computer survived the brownout and then blackout, but the fans didn't spin back up when power returned...so it burned itself up. Later I found one problem with this new system. It wouldn't resume after losing power. No BIOS setting to alter this behavior and I did try to see if there was alternate BIOS updates for it. It was kind of a painful machine to manage, because for some time kernels didn't have built-in support for all the SIS chipset stuff in it....so an update would roll out, and NIC was usually one of the things to definitely go missing. Which made for fun to rebuild a custom kernel upgrade for it. Eventually it got stable.

But, needing essentials like DNS, DHCP to be available after an extended outage...I moved these to another server (originally an old Pentium 75, which has evolved into what is known as 'box' today). For the longest time it was RedHat 7.2, and then RedHat 7.3 when fedora legacy switched to only supporting 7.3 and 9 releases. It continued after fedoralegacy stopped supporting it, I was building some of the packages for it by hand...like bind (in response to the Kaminsky exploit). There were parts of my network that wouldn't function without LHAVEN...like an old Windows 2000 box that was barely functioning...(old Gumby).

I nearly lost it during the Icepocalyse....but I tracked down motherboard replacement for it from geeks.com. It was a slighty newer mobo, but equivalent chipset. It did have some things the old mobo didn't, like USB 2.0 support (I didn't use USB and still don't), support for 2GB of RAM instead of 1GB...so I upped it for better BOINC'ng. And, faster CPUs....so I upped from 2200 to 3000.

At one time, I had turned it off to do some upgrades...which didn't pan out. Tried to slap a gigabit card into it...didn't work. Wouldn't get along with the on board stuff, and the BIOS didn't have ways to get things out of the way enough. It also never fixed the resume after power loss issue. But, during this process it failed to power on....but after a couple days, it came back and I decided to upgrade its UPS and hopefully it would make one last outage. Well, there were several others since then where it came back afterwards. But, looks like this is the last time for it.

I tried to upgrade 'lhaven' more...

...was less than successful.

Back following the icepocalypse, I resurrected 'lhaven' by changing its motherboard. The new motherboard was an upgrade to the old one, but I wasn't taking advantage of any of it. But, in my mind I thought that someday I might.

Having finally upgraded the OS from RedHat 7.3 to Ubuntu 10.04....and being able to participate in all BOINC projects again, I decided that I might look at upgrading it finally.

So I went looking for the fastest FSB 333MHz CPU that I could put into it. And, went looking on eBay for one. After a few unsuccessful attempts, I went and bought an Athlon 3000+ (and an Athlon 2400+). And, while I was on there, I got a new CPU Heatsink and Fan and a 1GB stick of DDR333 memory.

I wasn't sure what kind of memory was in the machine, but somehow I thought it to be a 1GB stick of DDR333 (since I for some reason had an extra DDR333 1GB stick that I gave away recently)....but memory told me the machine had two slots, so I'm not sure why I didn't upgrade the memory to more than 1GB...

Well, turns out my memory was faulty (as was lshw)...the machine had two 512MB DDR226 memory sticks. Which I makes sense, since the old CPU was FSB266 (a 2000+)....guess that means I shouldn't have given away that 1GB stick of DDR333.

What I did was upgrade the memory to 1.5GB by putting the new 1GB DDR333 stick in the first memory slot, and a 512MB DDR400 stick in the second slot. I then looked at the CPU.

First I put the Athlon 3000+ in....and the new CPU heatsink/fan. It is a touch bigger, actually its a lot bigger than the old....not quite compatible with my case...though it should be a simple enough mod once I get everything working again. Except I didn't. No POST.

Now instead of subjecting some poor random forum to a long rambling thought, I will try to consolidate those things into this blog where they can be more easily ignored profess to be collected thoughts from my mind.
