Re: Two different machines and experiences installing and running Ubuntu
I've done three generations of LinUX boxes over fifteen years. My first such box, an Intel® Pentium Processor® 200-based mid-tower rig running Red Hat® Version 5, predated Ubuntu® (Warty didn't start development until 2001); it probably would not have run Warty.
My second box is a home hot rod that started life as a bone-stock Everex® TC2502 (VIA® C-7D CPU and matching chipset with UniChrome video) running a derivative of XUbuntu® 7.10 Gutsy distributed by the now defunct Good OS LLC; I did two major upgrades with the same Athena® 500W PSU and Advance Micro Devices® Athlon 64® X2 5600+ MPU, a short-lived one to an ECS® mobo with an nVIDIA® MCP78S and GeForce® 8400 (uncommanded shutdowns under 8.04-LTS cut this one short) and then to a Gigabyte® mobo with Advance Micro Devices® 780GX chipset and ATi® Radeon® HD 3200 planar video under 8.04-LTS i386, 10.04-LTS i386 and now 12.04-LTS AMD64.
My third box, an eMachines®/Acer® EL1210-09 (Advance Micro Devices® Athlon 64® LE-1620, nVIDIA® MCP78S chipset, nVIDIA® GeForce® 8200 planar video), started life as a Windows box; the stock Hitachi® HDD died after less than two years, taking the stock Microsoft® Windows® 6.0.6002 installation with it. It now packs a Shuttle® PC6300002 PSU, Asus® EN210/DI/512MD3(LP) upgrade video (nVIDIA® GeForce® 210), and a Western Digital® HDD running a tailored version of 12.04-LTS, AMD64 Edition, to run stably with its quirky hardware.
