There might be some confusion: the 860 is the Motorola MPC860 'PowerQUICC', whereas I think the IBM laptop has a model number of '860' Is it one of these ? http://www2.ibmlink.ibm.com/cgi-bin/master?request=salesmanual&parms=SMS&xh=aVxB3ceuwvyczq1USenGnN9332&xhi=usa.main%7Csalesmanual%5E&type=D&search=&title=T&product=7249 The 603e processor isn't too far off from the G3, and I don't think any of the differences would be exposed in the current FreeBSD port. > Perhaps we could lay out some plans as to how we _could_ go about adding support for > this chip? The most difficult task would be device support for the system controller, interrupt controller (if it isn't OpenPIC), and peripherals. While it is theoretically possible to use OpenFirmware for all i/o (i.e. NetBSD's ofwppc port), that would be hideously slow, so I think you'd have to extract h/w info from Linux source. There's some good info on getting Linux to work on these machines at: http://penguinppc.org/projects/ later, Peter.
