[PATCH] sparc64 add cpuid to cpu node
by Igor Kovalenko 23 Dec '08

23 Dec '08

Hi! Linux kernel expects at least "cpuid" property in cpu device node, or it halts execution. This patch adds one with dummy "1" value. This allows to make some progress into booting the kernel. Please apply. -- Kind regards, Igor V. Kovalenko

Open-Bios on a compaq R4000?
by Spencer Hall 27 Oct '08

27 Oct '08

Hello, I have a compaq R4125CA with an AMD 3800+ CPU on socket 939. I would like to put in an AMD 4000 X2, but unfortuantely there is no bios support to activate the second core. I have read of other people putting a dual core processor in this same model and having it operate with just one core. Does anyone know what the possability of getting open-bios running on this system would be and activating the second core that way? Also, would it be possible to write a hook or patch the existing compaq bios to activate the second core? Maybe some code executed pre OS boot, like in the boot loader? I'm not sure how involved it would be to activate the second core, if tables must be set or just registers set, etc? I've been toying with this notion for awhile and have recieved some discouraging comments of the laptops ability to handle the heat dissipation, but I think it can handle it witha few updates to the thermal module and some high quality thermal paste. I'm not too concerned about battery life. Thanks, Spencer

OpenBIOS to replace outdated laptop bios
by J.P. Trosclair 15 Oct '08

Hi folks, I found this project looking for ways to add 48bit LBA support to an x86 laptop. The laptop was manufactured ~2005 give or take to the best I can tell. Anyway, it will not recognize more than 137GB of a hard drive (tested with a brand new 250GB WD drive). The company that produced the laptop says they will not provide anymore bios updates for it and they also said they will not release any information or specifications regarding the motherboard so that leaves me with very few options for attempting to address this problem. The bios installed on it now is Phoenix 4.0 release 6 and it has no serial numbers or anything that I've been able to find to help identify the manufacturer of the motherboard, in fact, I'm starting to think the board was built by the company who sold the laptop. Based on my research, the laptop comes from a company called clevo who resells to companies that rebrand the computers. With that said, I'm wondering if the OpenBIOS project can help me to address the problem I've described. Thanks for any information, J.P.
