I found it at 0x3bc instead of the usual 0x378. I have now moved it to 0x278 and yet tw0 still doesn't probe it correctly: ppc0: using extended I/O port range PC873xx probe at 0x26e got unknown ID 0x4b ppc0: SPP ppc0: at port 0x278-0x27f irq 7 drq 0 on isa0 ppc0: Generic chipset (NIBBLE-only) in COMPATIBLE mode ppbus0: IEEE1284 device found /PS2/EPP/NIBBLE_ID/PS2_ID/Extensibility Link Probing for PnP devices on ppbus0: ppbus0: isa_compat: didn't get ports for tw isa_compat: didn't get drq for tw tw0 failed to probe at port 0x278 irq 7 drq 0 on isa0 Has anyone seen this before? Maybe the tw driver doesn't work with 4.3? /raj To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
