Yes, here it is.. pmap_extract() at pmap_extract+0x13a isa_dmarangecheck() at isa_dmarangecheck+0x7a isa_dma_init() at isa_dma_init+0xda ppc_isa_attach() at ppc_sa_attach+0x40 device_attach() at device_attach+0x69 bus_generic_attach() at bus_generic_attach+0x1a acpi_attach() at acpi_attach+0x9f8 (there's more but I imagine the above is probably sufficient). I took pictures, they are here http://www.gsoft.com.au/~doconnor/SNC00111.jpg http://www.gsoft.com.au/~doconnor/SNC00112.jpg If I put the parallel port in EPP mode then it works, I presume that's=20 because it doesn't require a DMA channel whereas ECP doesn't. I haven't=20 enumerated the possibilities though :) =2D-=20 Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C --nextPart1879003.vpk92dQYna Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.12 (FreeBSD) iD8DBQBKuwLM5ZPcIHs/zowRAns1AJ9qyiMq1e7R8JBqdEb+I1GK3FmWpQCdHyQ/ uGnzmIO/n74OyomreU3NRq4= =1w9K -----END PGP SIGNATURE----- --nextPart1879003.vpk92dQYna--
