I think all of the docs neccesary are available from IBM Pubs. the url is http://www.elink.ibmlink.ibm.com/pbl/pbl?PNL=PBLIC01&CTY=600&LNG=ENU &ORD=PBL80826IOD00536&SRHWRD=PS%2F2&SRHFRM=&SRHPRD=&PRD=ALL&SRHDTF= &SRHDTU=&FRM=ORD&FNC%3DSRH=Search&SRHDBN=000 The more interesting titles being S84F-9807-00 PS/2 TECH REF-SYSTEM SPECIFIC S84F-9808-00 PS/2 TECH REF-ARCHITECTURE S84F-9809-00 PS/2 TECH REF-COMMON INTERFACE S04G-3283-00 IBM PS/2 AND PC BIOS INTERFACE TECH REF S68X-2341-00 PS/2 AND PC BIOS INTERFACE TECHNICAL REFERENCE They also have the tech refs for XGA, Ethernet and various SCSI cards. Most of them are between $55 and $80. I for one would like to see a microchannel port and would be willing to help out, I am not sure if I know enough to be very useful but I would try. I am still working on Token-ring for freebsd despite most peoples opinions on token ring being dead, even though Olicom just released a 100Mbps token ring adapter :) Larry Lile lile@stdio.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
