well I now know why i get 0xff000000 for the set up device - its MBASE0 is 0x0000000 when we do xf86scanpci, and PCINONSYSTEMCLASSES(baseclass, subclass) is true hence pciCheckForBrokenBase gets called, which will set MBASE0 to 0xffffffff, and as only the top byte is writable (16Meg chunks) MBASE0 becomes 0xff000000. not that this seems to help me much. i'm just more confused now!! why on earth would mbase0 be 0, if its in use and /proc says the device's memory is at 0xfa00000???! really just posting this here incase anyone else ever wants to know... =) laters, Rob Taylor Senior Developer robt at flyingpig dot com Flying Pig Systems http://www.flyingpig.com Please avoid sending me Word or PowerPoint attachments.
