There are actually at least three ways for connecting an IDE HDD. See ide-m8xx.c: --- 8xx_PCCARD uses the 8xx internal PCMCIA interface in combination with a PC Card (e.g. ARGOSY portable Hard Disk Adapter), ATA PC Card HDDs or ATA PC Flash Cards (example: TQM8xxL systems) 8xx_DIRECT is used for directly connected IDE devices using the 8xx internal PCMCIA interface (example: IVMS8 systems) EXT_DIRECT is used for IDE devices directly connected to the 8xx bus using some glue logic, but _not_ the 8xx internal PCMCIA interface (example: IDIF860 systems) --- I am probably the only one using EXT_DIRECT. ;-) Drop me a line if you need schematics.
