Others start reserved * and acquire sensible semantics if set to 1 (eg cable detect). A few * exceptions exist, notably around the FIFO settings. * * One additional quirk of the VIA design is that like ALi they use few * PCI IDs for a lot of chips. * * Based heavily on: * * Version 3.38 * * VIA IDE driver for Linux.
