[Massimo Calò]

Hi,

 If I desable the blkmem(uncheck "<>ROM disk memory block device(blkmem)") ,
my system doesn't boot. I receive the following message :

>>         VFS: Cannot open root device "" or 00:00
>>         Please append a correct "root=" boot option
>>         Kernel panic: VFS: Unable to mount root fs on 00:00

Can you help me?

Thanks!
