Hi again,
The problem is that the kernel did not try to copy and decompress the
floppy into a ramdisk, like if the load_ramdisk=1 parameter was ignored.
I suppose there is no message about ramdisk before the lines you
mentioned.
Here are two explanations b) is very likely:
a) The SRM boot command:
"boot dva0 -file linux -flags "root=/dev/fd0 rw ramdisk_size=5120 load_ramdisk=1 prompt_ramdisk=1 "
was not typed on just one single line, or the load_ramdisk=1 or
prompt_ramdisk=1 was mistyped (the ramdisk_size is in fact not needed
anymore).
b) The boot command is too long for the SRM console and it truncates
it , you can try with just :
"boot dva0 -file linux -flags "root=/dev/fd0 load_ramdisk=1 prompt_ramdisk=1 rw"
and see if that works
If that still does not work try:
boot dva0 -flags i
this should give you an "aboot>" prompt
then type:
"linux root=/dev/fd0 load_ramdisk=1 prompt_ramdisk=1 rw"
Tell us how it works.
Regards,
Loic
