As much as I like using Linux, I freely admit that there are tasks that it is not at all well suited for. And since I was faced with such a task a while ago, I had to dig out the old Compaq system restore discs and put XP back on my tinkering system.
All fine and dandy for a week or so. Problem was, I got a missing file message when I finally got around to uninstalling all the resource-hogging backlog that HP/Compaq[1] feels compelled to install during a system restore[2]. A dozen unplanned restarts, a virus scan that can't read much of anything and a CHKDSK later, I've come to the conclusion that something is seriously wrong with this computer. (This was a week ago, Wednesday)
Rather than fuck with it overly much, I decide to just dig out the restore disks, grin and bear it. Like I've said, this is a tinkering system. I don't have anything on there that I need to keep.
So, I get them in and low and behold, I get
Actually, it said IRQL_NOT_LESS_OR_EQUAL. Since that particular jibberish made as much sense to me as that did to you, I got to looking and found that the likely cause was the computer having problem communicating with the expansion cards. When removing both of my expansion cards[3] didn't let me proceed (with either the restore discs or the XP Pro install disc that I located elsewhere), I went even more drastic. I went in to the BIOS and turned off everything that wasn't absolutely necessary to starting the computer. In other words, I let the computer use the processor, talk to the CD and Hard Disk, and put stuff on the monitor. At least this cured the IRQL. In it's place, though, was a BSOD[4] telling me the MEMORY_MANAGEMENT module failed. So I took a hint.
I pulled all 512 MB of memory.
Now, anyone who knows the basics about computers will tell you that - up to a certain point[5] - the more memory you have, the faster your computer is going to go. Conversely, the less memory you have, the slower your computer will go. You can use this to run a very - very - basic test to see if your memory is working. Basically, one at a time, in the first slot, you plug in each module and see if it even tries to boot, or if it fails.
You guessed it, one of my modules failed. Which wouldn't bother me so much if it hadn't have been the newer one.
So, I learned two things this week. The first being that after cleaning all the crap off of it, Windows XP Home Edition can and will run respectably for web browsing - albeit fairly slowly on anything multimedia - on 256 MB of RAM.
Of course, I didn't find this out all at once. You see, when I got everything sorted out, I went to connect to the internet. All my connections were snug, my ATI was pushing a strong signal at 1280 x 1024, and the modem was sitting unused, as usual. But for the life of me, I could not find my freaking network adapter. Or rather, I found it, plugged it in, and the computer ignored its existance.
By this time, it was closing in on bedtime last night, so I said fuckitall and went to bed. First thing when I got up, I sheepishly returned to the computer, entered the BIOS, and turned back on the onboard LAN.
Which brings me to both the second thing I learned, and the opening of this post...
I really need to remember to take better notes.
[1] Actually, it's not just HP. It's anyone who tries to sell you a computer these days... Dell, Gateway, IBM. I have no problem with preloaded software straight out of the box. But for goodness' sake, I wish they would package it separate from the operating system on their system restore disks (HP's practice of not including separate restore disks with your computer is an entirely different rant). When you reinstall - or repair - the OS, you shouldn't have to spend a half hour aborting various branded shite.
[2] I'm ont talking about the Welcome to Windows thing. To give you an idea of this, I turned on the computer. Windows Messenger; to be expected, that's an actual XP component. Then the little connect to the internet graphic pops up, which won't go away until you run through their options trying to sell ISP subscriptions. I don't need an ISP, I'm hooked up already. Then comes Compaq Organizer - a heavy-duty program that could have been a widget - which is basically your Start Menu's most used programs list, a free-floating search bar, and your bookmarks folder. A dozen shortcuts to WildTangent; gone. And then I can start getting rid of the trial software.
[3] An ATI Radeon 7200 video card and an Agere Modem, if you were curious.
[4] That is, Blue Screen of Death.
[5] That point being the top end of what the mainboard can recognize and deal with. Any more than that, and either the computer is going to start throwing errors or just ignoring what it can't see. In my case, that point is 1024 MB (1 GB) of memory. Actually, it's probably 2GB, but the manufacturer says limit it to 1. This is a tinker-toy, not a gaming rig. I don't need to go all that fast.
