*
* Promise Ultra33 cards with BIOS v1.20 through 1.28 will need this
* compiled into the kernel if you have more than one card installed.
* Note that BIOS v1.29 is reported to fix the problem. Since this is
* safe chipset tuning, including this support is harmless
*
* Promise Ultra66 cards with BIOS v1.11 this
* compiled into the kernel if you have more than one card installed.
*
* Promise Ultra100 cards.
*
* The latest chipset code will support the following ::
* Three Ultra33 controllers and 12 drives.
* 8 are UDMA supported and 4 are limited to DMA mode 2 multi-word.
* The 8/4 ratio is a BIOS code limit by promise.
*
* UNLESS you enable "CONFIG_PDC202XX_BURST"
*
