** This is the quasi-official and semi-temporary T13 email list server. ** I can find nothing in ATA/ATAPI-6 that specifies the initial state of the nIEN bit... What is the proper setting of the nIEN bit following Power On Reset and Hardware Reset? Does a device ever change the value of the nIEN bit on its own? My opinion is that nIEN is 0 at the end of a Power On or Hardware reset and the only other way the bit changes value is via a IOW- cycle that updates the Device Control register. *** Hale Landis *** [EMAIL PROTECTED] *** *** Niwot, CO USA *** www.ata-atapi.com *** -- If you have any questions or wish to unsubscribe send a message to Hale Landis, [EMAIL PROTECTED] To post to this list server send your message to [EMAIL PROTECTED] For questions concerning Thistle Grove Industries or TGI's list services please send email to [EMAIL PROTECTED]
