>Environment:
Toshiba Tecra 8100 laptop
>Description:
From NetBSD 1.5.1 i386cd image, I created 2 floppy diskettes with bootlap1.fs and bootlap2.fs.  Booting the floppies from my Toshiba laptop, I ran into the following errors:
"isa1 at pcib1panic: isaattach: ISA bus already seen!".

I tried patching the kernel during the boot as described in the install doc with the followings:
(from the bootlap symbol file the the symbols)
"write 0xc0249a84 (pcic_isa_intr_alloc_mask) 0x0a00
 write 0xc04b00b8 (pcic_isa_alloc_iobase) 0x300
 write 0xc0249c04 (pcic_isa_alloc_iosize) 0x0bf"

it encountered:
"vum_falut (0xc058efc0, 0x0, 0, 1)->1
 kernel page fault trap, code=0"
error.

>How-To-Repeat:
boot bootlap1.fs & bootlap2.fs images from a Toshiba Tecra 8100 laptop.
