Ooops, I've added some detection code October, 31th. It may break your hardware. Detection of your ZIP is done in NIBBLE mode, then according to your boot flags, EPP mode is required for transfer. First, try to set your bootflags to 0x3 to force PS2/NIBBLE mode and see if it works. Then try 0x1. Secondly, set 0x44 to your bootflags to force your chipset generic and avoid NS chips detection code execution. I completly forgot all this... please, give me some feedback. -- 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
