It's designed to run with FPM ECC PS/2 Simms at 70ns. But it shouldn't matter if you plug in EDO Simms as the chipsset can't interleave - the board is single banked anyway. BTW - I had a test installation on IDE 1-2 years ago on my PC164. So yes - it should boot FreeBSD from IDE. > > Hi Andrew, > > I tried booting from IDE immediately after the power-on, but got > > the same result every time I tried. > > The exact machine error is a "660 Machine Check," which from my > > searching indicates a memory error.

All Simms must be of the same internal organisation. -- B.Walter COSMO-Project http://www.cosmo-project.de ticso@cicely.de Usergroup info@cosmo-project.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
