| Apollo PLE 133 Chipset VT8601A North Bridge Datasheet, Rev. 1.82, October 22, | |
| 2001, available from VIA: | |
| http://www.viavpsd.com/product/6/15/DS8601A182.pdf | |
| The datasheet is incomplete, some registers that need to be programmed are not | |
| explained at all and important bits are listed as "reserved". But you really | |
| need the datasheet to understand the code. "p. xxx" comments refer to page | |
| numbers of this document. | |
| XFree/XOrg drivers are available and of good quality, looking at the code | |
| there is a good idea if the datasheet does not provide enough information | |
| or if the datasheet seems to be wrong. | |
