I have an ide drive connected on my PC164: atapci0: port 0x10380-0x1038f irq 5 at device 11.0 on pci0 ata0: at 0x1f0 irq 14 on atapci0 ata0: interrupting at ISA irq 14 ata1: at 0x170 irq 15 on atapci0 ata1: interrupting at ISA irq 15 ad0: 1219MB [2477/16/63] at ata0-master WDMA2 hw.chipset.type: cia/bwx hw.chipset.bwx: 1 No problems so far with all OS versions I'd ever run. But I'm running -current (9th July) and rarely use the drive. I have no idea how different the PC164 is from the PC164LX beside the memory interface and the higher CPU clockrates. Note that PC164 boards on 4.x are running swiz due to a bug you had fixed for -current. -- B.Walter COSMO-Project http://www.cosmo-project.de ticso@cicely.de Usergroup info@cosmo-project.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
