I gotta go but you're taking a page fault in 9load it seems? Any chance your plan9.ini is messed up? I keep telling people ... pbs should load a kernel, then we don't have to debug BOTH 9load and a kernel :-) ron ^ permalink raw reply [flat|nested] 7+ messages in thread

The other report had the same thing.

You've got a problem with BIOS I/O. I wonder what it is? ron ^ permalink raw reply [flat|nested] 7+ messages in thread

There are two new plan9.ini options: "*nobiosload" to disable loading kernels via bios0 or sdB0, and "*noahciload" to disable loading via AHCI (native SATA). ^ permalink raw reply [flat|nested] 7+ messages in thread
