Mike, you seem to understand this well, I do not :) I'll have to if I want to make ppbus drivers run all together. So I hope Bruce is reading this mail too... I know we discussed about it, I have the mails here. So, is there any tutorial about how spls are working? Or which are the related files in the tree? > >Nicolas should probably look at this one... > Why does the system freeze like this? Is it permanently interrupted by an incorrect parallel port line level? BTW, what's the interrupt 'level' (I should say 'set' maybe) of dev_null drivers which are not said tty, bio or net in the MACHINE file? >-- >\\ Sometimes you're ahead, \\ Mike Smith >\\ sometimes you're behind. \\ mike@smith.net.au >\\ The race is long, and in the \\ msmith@freebsd.org >\\ end it's only with yourself. \\ msmith@cdrom.com > > > >To Unsubscribe: send mail to majordomo@FreeBSD.org >with "unsubscribe freebsd-current" in the body of the message > -- nsouch@teaser.fr / nsouch@freebsd.org FreeBSD - Turning PCs into workstations - http://www.FreeBSD.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
