Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii X-Mailer: Mutt 0.92.14i Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Hi All, Seemed that this may be the place for more of a technical discussion, as opposed to many of the other groups where one can expect 'Whats a DMA?'. I have recently aquired a Tyan Tomcat II Dual Pent. MB. Looks nice, wish I could say it works the same: I am having no end to troubles with it in regards to DMA and IRQ timeouts. I have set the Award BIOS to 'manually controlled resources' as opposed to PnP (evil, wish I knew about this before). The odd part is: everyting bloody well works fine until the kernel attempts to probe the IRQs/DMAs. It will read absolutely everything, even report ATAPI status on the CDROM and single IDE drive within (IBM DHEA EIDE), but a simple disklabel has it locking up (an attempt to boot from 3.0-SNAP, May 24, 1998 will cause it to panic, init dies and jordy's graphic laden fiend of an install program resets the box. If any Tomcat users could shed a little light what they had to do to make it work, it'd be greatly apprecated. Right now Im limping by from a small partition on my 2940 emergency backup, which seems to lose devices every reboot with this @_(#$@#$@# board.
