You can get filo only under Etherboot. make bin/filo.zelf or make bin/tg3--filo.zelf Also I added something into the filo in Etherboot. Regards YH -----Original Message----- From: Ronald G.

But we've had uneven luck building a working etherboot here. And ETherboot still does far more than we want. I would need to put the same kinds of mods into etherboot, and then build etherboot in a way in which all the ethernet support is not compiled in. In other words, I want to compile an etherboot down to FILO! It is simpler to just use FILO directly. ron

Then it branches to 0x4000 into _start, which sets up the stack and calls hardwaremain. The address of hardwaremain from linuxbios_c.o is wrong. The address is not the Flash address and it's not the RAM address. Can someone explain how linuxbios_c.o is linked with RAM addresses? Steve

RE: Kernel for linuxbios

Two things strike me as odd. 1. Your ," PCI: IRQ 0 for device 0000:02:00.1 doesn't match PIRQ mask - try pci=usepirqmaskPCI: 02:01.0 [1022/7462] disabled" Type of errors. Looks like you pcirqp map is bad? Are you making your Own mother board? If so it is important that you get this and the mp Table correct based on your wiring. 2. You did get to initramfs, good job, but it did fail to mount you File system. This could be anything. Please send your init script And Describe what are you trying to mount. A USB stick, ide, what? -----Original Message----- From: Sagiv Yefet [mailto:sagivy@3vium.com] Sent: Sunday, October 31, 2004 5:45 AM To: Dave Aubin Cc: linuxbios(a)clustermatic.org Subject: RE: Kernel for linuxbios I took your advise and try the 2.6.
