The only reason is to return the EISA probe to a read-only probe. The ahc VL cards require that their ID0 register be written too prior to reading the ID byte. This isn't required for true EISA cards and may prove harmful to other devices that just happen to be in that space. For instance, some PCI devices can be identified as EISA cards if you probe the full EISA bus blindly. -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
