Set BIOS address parameter

[Jeff_59]

Hello everybody

I just wanted to change the Bios address parameter, so i tried this undocumented command:

VBoxManage setextradata "myXP_VM" "VBoxInternal/Devices/pcbios/0/Config/DmiBIOSAddress" "0xF0000"

The command was accepted, so it looks as if it does exist. Unfortunately i got an error when i tried to
run the VM. Just wondering: is there a way to fix the error:
---------------------------------------------------------------------------------------------------------
Invalid configuration for device pcbios device (VERR_PDM_DEVINS_UNKNOWN_CFG_VALUES).

Code d'erreur : NS_ERROR_FAILURE (0x80004005)
Composant : Console
---------------------------------------------------------------------------------------------------------

Regards,

Set it again with an empty value, it will reset it to default

You can set almost any string in a "setextradata" field - they're just storage. The fact that it's accepted doesn't imply that it'll do anything useful.
