Hello, I'm wondering if anyone has any suggestion of any boards that are supported by linuxbios and have AGP graphics, audio and possibly onboard network (though eventually I'd like to add wireless networking instead). In a small form factor, like a SBC type setup. If you do that would be great. -- Nathanael Noblet Gnat Solutions 4604 Monterey Ave NW Calgary, AB T3B 5K4 T/F 403.288.5360 C 403.809.5368 http://www.gnat.ca/

VxWorks boot
by Felix Radensky 03 Mar '03

03 Mar '03

Hi, folks After a break I'm back to my task of using LinuxBios to boot VxWorks and I have the following problem. As I mentioned in my previous posts, VxWorks loader insists on beeing loaded at physical address 0x8000. The loader image size is 576K, and when loaded to 0x8000 it overrides areas used by LinuxBios itself, so I cannot even reach the code in LinuxBios that jumps to kernel entry point. I have verified that 68000 bytes can be copied to 0x8000, but 70000 cannot. If I'm reading ldscript.ld correctly, LinuxBios uses memory at 0x4000 for its data+bss, heap and stack. My question is: how can I modify this file to allow loading of VxWorks bootloader. Any other ideas are also welcome. TIA. Felix.

PCD-897-Bare with one DOC
by Gregg C Levine 02 Mar '03

02 Mar '03

Hello from Gregg C Levine Here's a question that I think someone can answer. I've recently obtained a PCD-897-Bare from an individual that I know on the Linux-MTD list. The Disk On Chip was formatted as a 2MB device, with the first 4K as the boot code, and at that I'm guessing. Now here is the question: How can I reset it from being reported as a Drive C device, to a Drive D device? I can provide the details of the host computer, on request, and off list. ------------------- Gregg C Levine hansolofalcon(a)worldnet.att.net ------------------------------------------------------------ "The Force will be with you...Always."

Hi Ron, I've updated the patch slightly to add a routine to enable flash writes on the epia mainboard with out the need for the seperate setpci command. Mark On Friday 28 Feb 2003 22:13, Ronald G.
