Hi,

I'm a new Plan9 user (still in the steep part of the learning curve),
and I've run into an already known problem :

    biosdiskcall: int 13 op 0x42 drive 0x80 failed, ah error 0x80
    sectread: bios failed to read 512  @ sector 0 of 0x80

I have an Intel DG45FC mini-ITX board. Same problem with MS Virtual PC.

Commenting out the following call in sectread() (src/boot/pc/devbios.c)
solves the problem :

    biosdiskcall(&regs, Biosdrvrdy, 0, bdp->id, 0);
