Hi,
I was trying to fix the Compaq Alphaserver DS10 target for LinuxBIOS.
While doing this, I moved the linuxbios table handling to from the
i386 directories to src/boot/
I attached a patch, and it doesn't break the other targets, plus it
builds nicely on Alpha again. But I haven't dared testing yet, as
none of the three DS10s I have here comes with a socketed flash and
unlike most other alphas there does not seem to be a built in FSB
(or does anyone know of one? Help on this is greatly appreciated)
I think the one or the other edge needs a bit of fiddling, but I hope
it's ok as a rough path. Eric, can you look into it and point me to
the (hopefully not too) many mistakes I made?
Stefan
