[OLPC-devel] status with linuxbios and currnet and marcelo's boot code and jordan's kernel

Sun Jun 25 18:40:04 EDT 2006

I can do the following:

kernel file is: vmlinuz-2.6.16-1.2289_FC6
kernel cmdline is: root=/dev/ram rw console=ttyS0,115200 
earlyprintk=ttyS0,115200,keep
kernel initrd is: initrd-2.6.16-1.2289_FC6-desktop.img
change any option? (Y/N)

In other words, I am able to boot linux in flash, and use marcelo's boot 
loader idea + kexec etc. to boot a new kernel.

Then from there ...

it knows how much memory there is ... I did set it to 100 when I created 
the args from mkelfimage.

And things don't go well with the initrd ...

well, that's not bad. I will try poking around some more.

Note that this is the olpc devel usb stick, with three partitions. I am 
going to try it without the initrd and see how it goes. But a LOT of 
stuff is working ...
