Something must be wrong mapping the bios:
101 /*
* Check if the machine has an EISA bus.
*/
/* Map the 128k BIOS region. kvtophys() should equate
* BIOS_START & PHYS_BIOS_START, but just in case, we
105 * track them both.
*/
if (osenv_mem_map_phys(PHYS_BIOS_START, BIOS_SIZE,
(void**)&BIOS_START, 0))
panic("linux_init: unable to map physical memory");
110 osenv_log(OSENV_LOG_DEBUG, "BIOS mapped to 0x%x\n", BIOS_START);
kaddr = (void *) (BIOS_START + trunc_page(0xFFFD9) - PHYS_BIOS_START);
oskit-20000202 has:
kaddr == 0xff000
oskit-2000901 has:
kaddr == 0xff000
<<snip>>
124 /*
125 * Initialize drive info.
126 */
127 if (osenv_mem_map_phys(0, PAGE_SIZE, &kaddr, 0))
128 panic("%s:%d: unable to map phys memory", __FILE__, __LINE__);
oskit-20000202 has:
kaddr == 0xdadf000
however oskit-2000901 has:
kaddr == NULL
129 x = *((unsigned *)(kaddr + 0x104));
130 addr = ((x >> 12) & 0xFFFF0) + (x & 0xFFFF);
131 if (osenv_mem_map_phys(trunc_page(addr), PAGE_SIZE, (void **)&x, 0))
132 panic("%s:%d: unable to map phys memory", __FILE__, __LINE__);
