- This driver adds up to 4 more EIDE devices sharing a single
- interrupt. This add-on card is a bootable PCI UDMA controller. Since
- multiple cards can be installed and there are BIOS ROM problems that
- happen if the BIOS revisions of all installed cards (three-max) do
- not match, the driver attempts to do dynamic tuning of the chipset
- at boot-time for max-speed. Ultra33 BIOS 1.25 or newer is required
- for more than one card.

IDE subsystem has been deprecated since 2009 and the majority (if not all) of Linux distributions have switched to use libata for ATA support exclusively. The replacement driver (pata_pdc202xx_old) has been available since 2006 and it supports all the hardware supported by the old pdc202xx_old host driver. Remove the deprecated pdc202xx_old host driver.
