Hi, I need help (and hope to get it quick ;)) to resolve the following problem. I've been experimenting with Open Firmware scripting and in the process I wrote some instructions to nvramrc that made my Pegasos to stop booting. I've connected the serial console and I see that the OF starts fine. It reaches the memory tests, passes it displays CPU info and then I assume it tries to start nvramrc. I then get an error (I've tried to find out something and in the test process made it to setenv something which gives the error). Then it shows:
no/bad nvramrc - performing default startup script nvramrc error nvramrc script error: undefined word no console: error: cannot open console for I/O no keyboard! error: cannot open keyboard for console input entering main read/eval loop...
And then I just get OF prompt. It seems it works almost fine. However it does not display command results (just error messages). Of course I can't start nvedit to correct the error I made. It seems also that other devices are not initialized too - I can't force it to boot or do any other job. So I need someone with better experience (maybe someone from bPlan) to help me resolve the problem. Is there any way to hand-init the console? Or maybe there is some simple way to reset nvramrc settings?
I was just told that when you press ESC just after the first keyboar led blink on power up it should bypass the nvramrc processing. Unfortunately it doesn't work for me.
Yes I did. Thanks. And you know what? The problem taught me nothing - I am still willing to mess with nvramrc to make my Pegasos recognize my new disks right after I boot it without additional reset.
What I found out using the serial console is that nvramrc is executed before harddisks detection (during disks spin-up). I'll try to add some delay loop to the nvramrc (as I couldn't find OF Forth equivalent of sleep/wait/pause command) to make it wait a few seconds before disks detection - I hope this will be enough for the disks to spin-up.
