103: * This front-end driver is really sort of a hack. The AHA-284X likes
104: * to masquerade as an EISA device. However, on VLbus machines with
105: * no EISA signature in the BIOS, the EISA bus will never be scanned.
106: * This is intended to catch the 284X controllers on those systems
107: * by looking in "EISA i/o space" for 284X controllers.
108: *
109: * This relies heavily on i/o port accounting. We also just use the
110: * EISA macros for everything ... it's a real waste to redefine them.
111: *
112: * Note: there isn't any #ifdef for FreeBSD in this file, since the
113: * FreeBSD EISA driver handles all cases of the 284X.
