Well, I was hoping not to have any Mac OS on this machine except a full-blown Mac OS 9 when needed. This would allow me to Quik-boot Linux and set OF to use /AAPL,ROM when needed through my serial console. I don't believe I can choose between booting Linux/Mac OS in any other system using a serial console (only built-in monitor). >>> >>> My suspicions were aroused when, after disabling CONFIG_FB, the machine >>> booted cold without any problems whatsoever. > > And what display? Well, I usually use the built-in one, but when I disabled CONFIG_FB, I didn't use a display, I just used my serial console / telnet. >>> >>> Is it at all possible to use Valkyrie without going through OpenFirmware at >>> all?

It just didn't make it into the official 2.2.18 tree. But > most users of valkyrie probably don't care anyway. I haven't tried the 2.4 tree because I didn't know how reliable it was. I guess it's time to try it now. How/where do I get it? You say that these changes didn't make it into the kernel.org tree, but where do I get the BK images? Is there a way of getting it through FTP/HTTP? Thanks, -- .-. Chris Boot /v\ bootc@worldnet.fr // \\ /( )\ L I N U X ^^-^^ >Phear the Penguin< ** Sent via the linuxppc-dev mail list.
