Digital Multia
Specs
Character TraitsMultias are almost infamous for their unreliability, and "heat death " is supposedly pretty common. I therefore replaced the puny factory-fitted fan with a meatier model, and put a heatsink on the 74623 chip. Unfortunately, I had the fan blowing air over the CPU to start with, and the machine started to cut out and make strange clicking noises when the weather got warmer. I then fitted it the other way round, drawing the hot air from inside the box outwards, so the machine ran pretty cool. Unfortunately this machine is now very unreliable and hangs making a strange clicking noise every now and again. I therefore took it out of service and raided it for parts for other machines. Expandability was not the top priority for the designers of this little machine. There is one rather delicate-looking PCI riser board, which cannot be used in conjuction with an optional 3.5" hard disk. In my example, even the CPU is soldered to the motherboard. Some models (not this one) have an expandable cache. Mods
Installation and ConfigurationThe Debian installation boot disk didn't work, so I used one from Red Hat 7.1 with the Debian RAM disk image. However, as this machine has no CD-ROM drive, I still needed the modules for the 2.4 Red Hat kernel to get networking up and install via HTTP. I got these from the Red Hat RAM disk image - this can be gunzipped and mounted as an ext2 filesystem through a loopback device. The modules can then be extracted from the cpio archive in this filesystem. The installation itself is very minimal - just enough to get networking, SSH access and iptables-based firewalling/NAT up. |
