Special UDMA Feature
CONFIG_PDC202XX_BURST
- For PDC20246, PDC20262, PDC20265 and PDC20267 Ultra DMA chipsets.
- Designed originally for PDC20246/Ultra33 that has BIOS setup
- failures when using 3 or more cards.
+ This option causes the pdc202xx driver to enable UDMA modes on the
+ PDC202xx even when the PDC202xx BIOS has not done so.

- Unknown for PDC20265/PDC20267 Ultra DMA 100.
+ It was originally designed for the PDC20246/Ultra33, whose BIOS will
+ only setup UDMA on the first two PDC20246 cards. It has also been
+ used succesfully on a PDC20265/Ultra100, allowing use of UDMA modes
+ when the PDC20265 BIOS has been disabled (for faster boot up).
