I've seen this used with FORTH code in order to automatically identify the correct device, after a failure to load modules from the wrong "guess". The "guess" comes from the BIOS. THere are some Dell systems where the BIOS doesn't set up the BX register correctly; I don't know if there are any systems besides Dell where this is an issue. -- Terry To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
