BIOS initialisation stores the index port number in the Graphics + * register bank (0x03CE), indices 0x50 and 0x51. Unfortunately, for all but + * the 18800-x series of adapters, these registers are write-only (a.k.a. black + * holes). On all but 88800's, the index port number can be found in the short + * integer at offset 0x10 in the BIOS. For 88800's, this driver will use + * 0x01CE or 0x03CE as the index port number, depending on the I/O port + * decoding used. The data port number is one more than the index port number + * (i.e. 0x01CF). These ports differ slightly in their I/O behaviour from the + * normal VGA ones: + * + * write: outw(0x01CE, (data << 8) | index); (16-bit, not used) + * outb(0x01CE, index); outb(0x01CF, data); (8-bit) + * read: outb(0x01CE, index); data = inb(0x01CF); + * + * Two consecutive byte-writes to the data port will not work. Furthermore an + * index written to 0x01CE is usable only once. Note also that the setting of + * ATI extended registers (especially those with clock selection bits) should + * be bracketed by a sequencer reset. + * + * The number of these extended VGA registers varies by chipset. The 18800 + * series have 16, the 28800 series have 32, while 68800's and 88800's have 64. + * The last 16 on each have almost identical definitions.

If we had more data registers, + * then we could do better. If XAA supported a trigger write + * address, the code would be simpler. + * (Alan Hourihane) Update.
