Re: epia800 direct vga working
Hello, So I've got the epia800 working with the original BIOS that was extracted from the original BIOS. I've been looking over the code that was submitted, and as well as the difference between register settings on boot with regular BIOS settings and LinuxBIOS settings. I have been trying to get DirectFB to work with the epiafb module. It works when I boot with regular bios, but not the LinuxBIOS version. Here are the differences between the two.

Once I have that all working like the original bios I guess the direct vga changes could incorporate the changes and we would not need the VGABIOS if I am not mistaken? I'd like to help, but need to know how to go about reading the above in a better way then I know right now... -- Nathanael D.

error snapshots download.
So I downloaded the cvs snapshot referenced from the new wiki. It seems to be a copy of the repository, and not a checkout.(files are .v ) with all sorts of version information. Just a FYI. -- Nathanael D. Noblet [EMAIL PROTECTED] Gnat Solutions ___ Linuxbios mailing list Linuxbios@clustermatic.org http://www.clustermatic.org/mailman/listinfo/linuxbios
Re: Booting Linux using netboot and HD

I have one more question on the comment Peter made, Peter Wrote: Indeed, this is another option. But a new kernel is still neccessary since the one in the ELF image (/boot/initrd-2.4.20-8smp.img) came with neither ext3 nor IDE drivers. My question is, if initd-2.4.20-8smp.img doesn't understand ext3 and don't have IDE driver, why I can boot everything from HD using AMI BIOS? The initd-2.4.20-8smp.img is the same for both LinuxBIOS boot and AMI BIOS boot. I assume after ramdisk loaded, Kernel would rely on Linux IDE driver and no longer make any BIOS hard drive service call, right? Correct. If you ask me, you have two possible problems. 1) LinuxBIOS isn't setting up the IDE controller properly so that your kernel can't find it or 2) Something in the moving the kernel and initrd to the tftp server/system didn't work. As you are trying to ultimately boot directly from the local machine, I would use FILO. You may also want to post the kernel message on boot (all/most of them) so that developers here can see if there is something they recognize as being in error. I won't be able to help you unless it is obvious. I just find setting up a FILO boot to be easier then the network kind, which is likely because I understand it better, and have done it more. -- Nathanael D.
