Description (last modified by )
I've been trying to boot Haiku on my main machine with no success. The build I've tried is hrev43475 GCC2H off of haiku-files.org burned to a DVD.
Specs of the computer: Core i7-2700k (Sandy Bridge) Gigabyte GA-Z68X-UD4-B3 16 GB DDR3 RAM GeForce GT210 VGA (PCI-Ex) with 512 MB OCZ Vertex 3 SSD
Symptom: When booting normally, no boot icon lights up. I've tried booting with preety much every combination of safe mode flags to no availability. While booting verbose, the last lines it outputs before stalling (No KDL, nothing) are 7 lines similar to the ones that start with "PCI: dom 0, bus 0" in this photo: http://dev.haiku-os.org/attachment/ticket/8111/1.JPG
Extra Info: Due to my wanderings with booting multiple OSes, I've found a similar behaviour with OS X where it also stalls at "PCI Configuration". There was a fix provided by the developers which was to add a parameter to the bootloader, namely "npci=0x2000".
All the info I could find about that parameter is this tidbit
"0x2000 is the kIOPCIConfiguratorPFM64 flag, as seen in the IOPCIFamily source code. (PFM64 probably stands for prefetch memory 64 bit).
npci=0x2000 turns off this flag, as npci negates whatever flag bits you specify. With this flag turned off, the logic that sets fConsoleRange is disabled, and so the new graphics console relocation code is not triggered. However, the rest of the other new relocation code is still executed, and therein probably lies a problem for some, depending upon your PCI memory config."
I've attached some logs from Linux (lspci, lsusb & lshw) since I was unable to get into KDL and not having a camera also didn't help regarding taking a picture of where it stalled.
Also, according to Disreali, this might be similar to the bug #8111 but since that one does go into KDL and mine doesn't (also, the user there is an AMD user and this is an Intel CPU) I thought it'd be better to create a new bug report.
