gao, this is a boring read but I was amazed at the cross compatibility and ease of hardware musical chairs in upgrading my linux systems.

Well I've been doing computer brain, lung and heart surgery today. I got two 866eb slot 1 yesterday. There were 104 a piece. Open box retail units. I earlier had picked up a couple of epox ep-6vba2 boards for 28. I had built up a system using the disks and from a p-pro system and I took one of the cpu's from my portable system
watman.com. called angle.

In the new system I call half I installed nt 4.0, w2k pro and redhat 7.2 called release enigma. After getting the new cpu's I put the an 866eb in half and replaced the 650e back in angle with it's twin 650e.

I then decided to replace the supermicro dual mother board on angle my portable display system with the other epox motherboard the 2nd 866eb cpu. The mother board swap went with no hitches and the system booted perfectly as if nothing had changed. Angle the portable system is a dual sgi flats display system. It runs mandrake 8.0 linux.

With the dual super micro board I decided to upgrade my dual analog display work computer called accute. watman.com shows acute. Well the only thing that really makes acute is the hard disk and the software. Acute has a 15 gig Ibm drive and is running redhat 5.2. I've also been wanting to upgrade acute but I like to do that with different hard disk so I can always fall back if something goes wrong. Acute is my main work and email and systems and network monitoring system.
'
Trading is done on watman.com. That's square linux mandrake 6.1, 600e PIII with a gig of memory. Also obleak a nt 4.0 200mhz dual P Pro with 192 meg Each system drives two sgi flat's.

So I decided on a somewhat more complex and indirect path to upgrade. I installed the epox motherboard in a new case. I have extra matrox video cards so the Xserver and gui would be no problem. I had a different ethernet card and I cover that later. I also added a sound card. But speaking of amd I had an amd k??? 200mhz and back when I acquired 4 64 meg simms and this k??? was the only motherboard that could recognise them as 64 meg. This is a few years back and I had standardized on a Intel venus P Pro motherboards. I acquired a dozen of so for 8 bucks a piece. these boards would perform as well as Pentium II up to 450 or so. The P Pro had a very cost effective performance sweet spot for a couple of years until late 99, early 2000. Now I also had an ultrawide tekram scsi and a 10 gig hard drive from way back and this would only run in the K???. So for a while I ran the K??? with the 10 gig scsi. Anyway the k??? went flaky and I just shut the system down a while back.

Well I decided to try the Ultra wide tekram controller and the 10 gig scsi with the dual super micro board. Well I put them together told the mother board to boot scsi and all worked fine. I then got a 100 baset ethernet card from the k??? case and ehernet came right up at boot. I also looked around and found a 6x scsi cdrom and a 4x scsi cdrom and added them to the system. All worked well.

Now I was ready to get the the second video card and hard drive from Acute. Well all was assembled and the scsi would boot fine. When I tried to boot the ide driver that is acute the drive would hang. So I booted the scsi drive which also contained 5.2 linux. I the did an fdisk of the ide drive that is system acute. Well the hard drive was not being detected correctly by the bios of the supermicro motherboard. So I booted several times and finally manually set the motherboard bios so the acute disk would boot clean.

Now however the network was not coming up as the network card configured for acute was different that the one being used now.

In linux device modules are loaded with the kernel. So I edited the conf.modules file.
[ 343 ] > cat /etc/conf.modules
alias eth0 3c59x
#alias eth0 eepro100
#alias eth0 3c509
All I had to do is add the correct module name for the ethernet card.
As soon as I had edited I did network stop and then network start and all was happy.

So acute is upgraded and working find. No longer a 200 mhz P Pro with 128 meg of memory. Now a dual 650e PIII with 512 meg. I'm going to upgrade the scsi with redhat 7.2. I've also added in a sound card.

Oh I love my linux.
