CONFIG_PDC202XX_BURST: Special UDMA Feature

General informations

The Linux kernel configuration item CONFIG_PDC202XX_BURST:

Help text

This option causes the pdc202xx driver to enable UDMA modes on the PDC202xx even when the PDC202xx BIOS has not done so.

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 successfully on a PDC20265/Ultra100, allowing use of UDMA modes when the PDC20265 BIOS has been disabled (for faster boot up).

Please read the comments at the top of drivers/ide/pci/pdc202xx_old.c.

If unsure, say N.
