Hi, all.
We adapted LinuxBIOS for Broadcom Explosion based on Blast LinuxBIOS. It runs well in LinuxBIOS phase, but in Linux phase, there are some problems. It seems the hard disk can't be found.

No, the hard disk was found (Maxtor 6E040L0). But no interrupt for this IDE controller device? -> "hda: lost interrupt" there is no answer. Recompile your kernel with DEBUG macro defined in "arch/i386/pci/pci.h". Run this new kernel with kernel parameter "irqpoll" and check your interrupt routing...
