*** Use of the "serialize" option is no longer necessary.
This is the multiple IDE interface driver, as evolved from hd.c. It supports
up to 9 IDE interfaces per default, on one or more IRQs (usually 14 & 15).
There can be up to two drives per interface, as per the ATA-6 spec.
================================================================================
Common pitfalls:
- 40-conductor IDE cables are capable of transfering data in DMA modes up to
udma2, but no faster.
- If possible devices should be attached to separate channels if they are
available. Typically the disk on the first and CD-ROM on the second.
- If you mix devices on the same cable, please consider using similar devices
in respect of the data transfer mode they support.
- Even better tru to stick to the same vendor and device type on the same
cable.

Primary: ide0, port 0x1f0; major=3; hda is minor=0; hdb is minor=64
Secondary: ide1, port 0x170; major=22; hdc is minor=0; hdd is minor=64
