- * 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"
