Re: [LinuxBIOS] Etherboot (FILO) with SATA on tyan s2895

So the vmlinux+initrd.gz--> elf, and nrv2b to be the payload... What is size of final elf? 1. bzImage+initrd.gz 2. vmlinux+initrd.gz --> nrv2b I wonder if 2 would be bigger than 1. YH

No FILO need... Use mkelfImage to put tiny kernel and initrd to make one elf. And LinuxBIOS can treat that as one payload and just like FILO and Etherboot. Someone (from F5) has used 2M flash ROM to put LinuxBIOS+kernel+initrd. You could do that if you want to spare the CF IDE flash. With the tiny kernel support, we can have support for all driver support in kernel for SCSI, USB, Firewire, iSCSI, AOE, IB, Myrinet, quadric...any media. We don't need to port the driver to the boot loader. And everyone could focus on driver in kernel instead of waste time to port driver back and forth. That is correct way. Just like we are talking about UEFI support. We could add the table and services in LinuxBIOS, but we like to run uefi as linux application on kernel to re use the driver in kernel. We don't need to spend dev time on FILO and Etherboot anymore.

I'd also like to be able to get to grub eventually. Is there a way to go from LinuxBIOS to grub more directly on the s2895? Thanks again for your help.

[LinuxBIOS] problem with compressed rom stream
by ron minnich 18 May '06

I have an nrv compressed filo.elf that on linux I can uncompress and have work. ~/src/LinuxBIOSv2/util/nrv2b/nrv2b d /tmp/filo.elf.nrv /tmp/xyz 39496 in linuxbios, the uncompress is too short: rom_stream: 0xfff90000 - 0xffff7fff Uncompressing to RAM 0x00200000 olen = 0x000062fc done. Cannot Load ELF Image print/x 39496 $1 = 0x9a48 Any idea what to look for? ron

[LinuxBIOS] EPIA non-M?
by Alex L. Mauer 18 May '06

18 May '06

What's the current status of LinuxBIOS on plain EPIA boards? It seems to be very unclear. The "Supported motherboards" Wiki page lists it, but has a lot of "???". The build tutorial page -- like all the others -- links to nothing. The FreeBIOS howto says it doesn't have VGA support, though that is of course two years out of date. When I build it, the generated BIOS image is 256k -- which doesn't leave space to prepend a VGA BIOS. So is the status of LinuxBIOS on these boards the same as it was with FreeBIOS 2 years ago? Thanks -Alex Mauer "hawke"

[LinuxBIOS] UEFI discussion
by Stefan Reinauer 17 May '06

17 May '06

Hi, I was about to have a look at implementing UEFI, when I noticed the following: I understand that I may download and read the UEFI 2.0 specification without the requirement of a license, and doing so creates no obligations or commitments on my part. I further understand and acknowledge that any distribution, additional reproduction, implementation or other use of the specification requires a license, which can be obtained by executing the UEFI Adopters' Agreement. Reading further, this means I have to pay a yearly (voluntary?) fee to be allowed to do anything with the UEFI spec. Is there any interest at all in an Open Source UEFI implementation? This discussion is popping up from time to time but it is never really getting forward yet. What do you think? Best regards Stefan Reinauer -- coresystems GmbH • Brahmsstr. 16 • D-79104 Freiburg i.

Then you have to look at efi support code in Linux kernel, and feed the code with it wants.

Re: [LinuxBIOS] COM2 in tyan/s2881

Good. That will make you boot time longer. Because the com2 only need to set to 19200. YH -----Original Message----- From: linuxbios-bounces(a)linuxbios.org [mailto:linuxbios-bounces@linuxbios.org] On Behalf Of Ward Vandewege Sent: Tuesday, May 16, 2006 2:46 PM To: linuxbios(a)linuxbios.org Subject: [LinuxBIOS] COM2 in tyan/s2881 Hi there, It seems COM2 is disabled by default in the s2881/Config.lb file. Since the board has a COM2 connector, and it is what you would use with the IPMI daughter card, would it make sense to enable it by default? I've got IPMI console redirection working by letting FILO 0.5 (in grub mode) and the kernel talk to COM2 instead of COM1. COM2 is connected to the IPMI card. With the latest ipmitool snapshot (http://ipmitool.sourceforge.net/snapshot/), that gives me have a serial console over the network without extra hardware (other than the IPMI card).
