Background Recap:
|
I inherited a
computer from my Grandfather who sadly died just
before Christmas. This is a story of what
happened to it. |
|
|
|
|
Read the story so far |
So far the Compaq has
had a lot of rebuilding work, if you want to
catch up, please look
here. |
|
The Plan
|
So the Compaq was
getting quicker all the time, but still it felt
a little choked. I thought it would be fun to
upgrade the processor. This is what happened. |
|
Buying the Kit
|
Okay so the Compaq
has got a Zero-Insertion-Force Pentium 1 socket
- I think it's a 7 slot, what I needed was
something I could drop in for a bit more ooomph.
I rooted round in the graveyard but the best I
could do in there was a 486DX2-66.
I remembered a
while ago I had thought about doing a chip
upgrade with a previous machine but never really
got round to it. At the time I had looked at the
Evertech range but never really went for it
at the time.
I used their
product chooser and they suggested a
Spectra 400. With a deal price of $79.99
down from the usual $179.99 (perhaps the
original price is what put me off before?).
Aaaanyway - BAAARGAIN!, so I ordered one and
paid the addition $30 for shipping. |
|
About 4 days later |
So the postman turns
up a couple of days later and I'm out,
apparently the parcel has incurred an additional
£25.00 of postage costs which need to be paid
C.O.D. I asked Evertech if this was normal and
they said that occasionally further costs may be
incurred. Fair enough. I paid the extra. |
|
Evertech first sight |
I opened the Evertech
Spectra box and beheld a thing of beauty. It was
a sweet little AMD K6 chip with a blue anodised
heatsink and a spinny fan on the top.
I got the manual
out of the box and put it aside (I'm a
programmer remember). In the box was also a big
installation poster, a floppy disk and a CD.
I put the floppy
disk into the Compaq and turned the machine on.
The Compaq booted from the disk and whirred and
clunked a bit for a little while.
Firstly the disk
said that I didn't need a BIOS upgrade (I wass
pretty pleased about this because I really don't
like flashing BIOS' and anyway I'd had enough
fun with all that malarky in
part one
of the adventure).
And then after a
bit more whirring and clunking it gave me some
benchmark numbers I wrote these down. |
|
Taking out the old
chip |
I took the top off
the Compaq (getting quite good at this bit now).
The CPU is at the front left corner. It shocked
me a bit because I hadn't noticed before that
the chip looked HUGE - double the size that I
thought it should be. I thought it was going to
get interesting, cos the new chip looked small
and the old chip looked HUGE.
I plinked the
heatsink clamp and lifted it off, underneath was
what I was expecting, a normal P1 size chip -
Compaq had put a double width heatsink on it -
they'd have been better off with a fan... but
you know compaq...
I flipped over the
ZIF lever and lifted out the old CPU - bless it
- it looked like it had worked hard in it's
life, the Heat Transfer compound looked like it
had boiled in it's time - lol.
So the Compaq was
all lined up and processor free ready for the
new chip |
|
Fitting the Evertech
Spectra 400 |
Well, I'd like to say
this couldn't be easier, and it couldn't have
been easier except one of the legs under the
chip was just sliiiiiightly out of line. I
gently bent the pin back with my programmers
screwdriver and the Spectra fell into the ZIF
socket with no problem.
I put the ZIF
lever back down and clamped the chip down with
the Evertech heatsink clamp.
There's a bit of
plumbing to do. You have to plug the fan lead
into the CPU riser PCB, ther's alittle socket on
one of the corners. And then you have to plug
the fly lead into one of the drive power
connectors. Easy to do - but if you dont you're
gonna fry something. |
|
Looking for Compaq
motherboard jumpers and DIP switches |
So now I was
wandering round the motherboard looking for
jumpers - I thought I would have to change
something. I looked on the web for a motherboard
jumper map for the compaq but didn't really find
anything. After about 30 mins of messing about I
gave up and flicked the ON switch.
I thought 'sod it,
shit or bust now'
The fan on the CPU
span up and the BIOS screen showed.
The system booted
from the Evertech floppy I had left in and went
back to it's benchmarking routine.
Things looked like
they might work.
I waited a bit as
the benchmarking went on. |
|
Benchmark results |
Okay, so the
Benchmark says that things are running :
2.7 times quicker
on the Dhrystone test, and
4.7 times quicker
on the Mediastone test
That looks like a
bit of a result really. |
|
Take the disk out and
reset to SuSE |
GRUB kicked in after
the reset and SuSE defaulted to its
initialisation.
Bliiimey it seemed
quick, rattling through it's setup
For the first time
I noticed the animation on the SuSE install
script screen.
After a short time
the User Log in screen appeared and so I logged
in.
KDE initialised
and the desktop was smooth with windows floating
around as they should, far more gracefully than
with the old chip in.
I set the default
screen saver to swarm and doubled the elements
and waited for it to kick in.
Before the
Evertech went in, this screen saver was very
jerky, with the elements jittering around the
screen. I thought that by doubling the elements
I would push the compaq a bit harder.
The screen saver
kicked in and it was as smooth as silk |
|
Result |
SuSE on the Compaq
feels like a whole new world, things are more
fluid and easier to use. The system as a whole
now feels that it isn't just running out of
breath all the time.
The Evertech
Spectra 400 upgrade was a piece of cake to
install in the Compaq and goes like stink. The
only slight fly in the ointment was a bent leg
on the chip. This could have happened anywhere,
manufacturing or transit. The manual gives
instruction on how to cope with this (bend it
back gently).
One note I made is
that in the manual there are a lot of caveats
about running versions of Windows on a Spectra
upgraded machine. I can't comment on this
because I haven't tried it - but most definitely
the speed increase on SuSE Linux is fantastic. |

Next... |
Meanwhile, back in
the real world.
The hard disk I
donored into the Compaq initially now seems to
be the bottle neck. As mentioned in part 1, it's
a clanky old Seagate 8Mb, I think that I might
buy a nice Maxtor (I like Maxtor HD's) and slap
it in, probably a 40Gb because they are pretty
cheap at the moment.
After that I dont
really think there is anything else I can do
with the hardware. I think thats it all maxed
out - I don't want to get into overclocking
malarky (I cant find any jumpers on the
motherboard anyway).
So I was thinking
I could set the Compaq up as a gateway machine,
and have it as the hub for my networks internet
connection. Because I've got SuSE Pro - It's got
all the firewall and malarky in it.
The problem is
that the modem currently in the Compaq is an
unknown make WinModed. I know there starts to be
some Linux drivers for these but I'll try and
find a proper modem. I'd really like to have a
go at shot-gunning modems onto a dual
connection.
It may be we get
broadband any minute anyway... |
