Then it contains isa_dmacascade function which does not : exist and is not needed for PC-98. Is that because there's not isa bus on a pc-98? Or that the adv_isa cannot possibly work on the ISA bus that is in a pc-98? If there's no isa on the pc98, then config should take care of not including it. So I'm a little confused here. If there is a isa bus, but it doesn't support dma, I think that we'd have problems with many different drivers, and not just adv. : The reason to comment out is to be clear that it is not required. If : it is completely removed from files.pc98, we may guess wrong in the : far future that we forgot to merge from files.i386. This part I understand. If it is a md file, then it makes sense to leave it commented out like you did. Warner To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
