We've started again with the MCA rs/6000's and I needed a bit of help. A little background on the machine- It's a rs6000 7011-250 with a 601 PowerPC processor The io ports on the MCA bus are addressed through a bus unit controller with a BUID of 0x20. If I wanted to write something to 0x3f8 on the mca bus, I would have to set up the segment register, etc, correct? Is this something with enough overhead that I can't realistically do it for every io port access? We do have some code by Andrew Richardson that will make a valid boot disk and print 987 to the display on the front. It's available at http://www.sjdjweis.com/bboard/q-and-a-fetch-msg.tcl?msg_id=000005&topic_id=1&topic=RS%2f6000%20Linux Any help is appreciated! dave -- David Weis | 10520 New York Ave, Des Moines, IA 50322 djweis@plconline.com | Voice 515-278-0133 Ext 231 | http://www.perfectionlearning.com/ ** Sent via the linuxppc-dev mail list.
