I talked to our local DEC people about our repeated crashes due to double tbuf parity errors, which are not handled by 4.2bsd. According to them, rev 6 of the 750 will completely fix this problem. Rev 6 can apparently be ordered (they are ordering it for our leased machine) and will involve 6 board swaps and new microcode. This isn't terribly exciting since most of what I heard from them I have heard elsewhere (including this network) before, but they also said that a method has been devised to allow UNIX to be able to load the microcode patches at boot time from the console cassette. It would appear that 750 w/unix would always boot from the cassette and that it will length the reboot time by 3 minutes (their figure). Has anyone heard more about this? Beta sites? DEC people? -- Chris Boylan {mgnetp | ihnp4 | uwvax}!dicomed!boylan
