The following may seem obvious, but here goes... |
17 |
|
18 |
* remove unnecessary video cards, and drivers. Most colo machines |
19 |
should do OK with just a text console running on the onboard GPU. |
20 |
Dump all video driver stuff "/dev/agpgart (AGP Support)" and |
21 |
"Direct Rendering Manager". This assumes you're not running X on |
22 |
your colo machines. mc (Midnight Commander) is a great text-based |
23 |
tool, along the lines of ye olde Norton Commander. |
24 |
|
25 |
* disable sound cards/chips in BIOS and remove drivers and kernel |
26 |
support. |
27 |
|
28 |
* Run "rc-update show" and look for any services you don't need. |
