I’ll have to double check, but I think that rombios picks up the smbios tables from 0xe9000 and copies them into the valid range. We do it that way because only rombios knows the memory layout 0xf0000-0xfffff.

By the spec it should be somewhere between 0xF0000 to 1MB,
There is even a comment in the code:
/* SMBIOS entry point -- must be written to a 16-bit aligned address
between 0xf0000 and 0xfffff.
*/
struct smbios_entry_point {
...
Any reason for that?
Thanks,
Guy.
