From: rlfnb Date: Tue, 3 Mar 2015 20:23:40 +0000 (+0100) Subject: ALIX: No pci device at bus 0, dev 0, func 0 X-Git-Url: http://zhaoyanbai.com/repos/Bv9ARM.ch12.html?a=commitdiff_plain;h=b56a9d4725f0b3aa743904042e3d84db4e9af7ff;p=minix.git ALIX: No pci device at bus 0, dev 0, func 0 Seems like its a kind of convention introduced by Intel but not mandatory from a PCI specification point of view, that the PCI host controller resides on bus 0, device 0 function 0. At least tinybios (the bios used by ALIX and WRAP) based appliances are not able to boot with this change.
