[LinuxBIOS] Support for Tyan s2915 or s2927

2007-04-12 Thread Arvind Seshadri
Hi, I am looking into building a personal workstation around the Tyan S2915 or the Tyan S2927 for LinuxBIOS hacking. I have been following the mailing list since January when Yinghai Lu posted a huge patch with support for the Tyan S2912, among other boards. From Tyan's webpage it seems that the

[LinuxBIOS] MSI K9SD Master-S2R (MS-9185)

Hi, I am looking for a Socket F motherboard that is compatible with LinuxBIOS. The MSI K9SD Master-S2R (MS-9185) seems to be the only one that fits the bill. A couple of questions: 1. Where can I find datasheets for the chipset on this motherboard (Broadcom BCM5785, Broadcom BCM5780)? 2. What is

Hi Carl-Daniel, Yep, the GART is one way to go. On the other hand, there are PCI-Express systems that do not have a GART. The whole thing is a bit of a mess, which is why I didn't expand on it. Cheers, Arvind On Fri, 12 Jan 2007, Carl-Daniel Hailfinger wrote: Hi Arvind, Arvind Seshadri wrote

[LinuxBIOS] SMM in LinuxBIOS

2006-12-26 Thread Arvind Seshadri
Hi, I would like to implement a piece of code as an SMM handler in LinuxBIOS. From what I understand of LinuxBIOS, there is no SMM handler at present but the SMM registers on the AMD K8 platform are locked using the SMMLOCK bit. How does the platform then handle SMI when using LinuxBIOS? I would
