[PATCH 2.4] Generic IDE support for more Toshiba Piccolo PCI IDEchips

[Daniel Drake]

Adds more Toshiba IDE chips to the list supported by the generic IDE driver,
for chips with product ID 0x0103 and 0x0105
This then allows DMA to be enabled on disks.

For more info, see:
http://www.uwsg.iu.edu/hypermail/linux/kernel/0401.1/0150.html
http://www.uwsg.iu.edu/hypermail/linux/kernel/0402.0/0129.html
(it appears that Ben's patch never appeared, and Jerome's got lost)

Against 2.4.27-pre1

Please apply,
