And I was so proud of myself. Is this documented somewhere? the only reference to dma i found was in the Supported PC Hardware page of the wiki, which suggests editing data.c. Speaking of the wiki, I notice that the instructions on the Acme Wiki Instructions are not working? There are some links on the site that are broken, ( e.g. the installation notes link on the http://plan9.bell-labs.com/plan9/ page points to http://plan9.bell-labs.com/wiki/plan9/installation_instructions/ instead of http://www.plan9.bell-labs.com/wiki/plan9/Installation_instructions ) and I thought to help fix that In any case, my system is now mostly idle and is no longer generating tens of thousands of interrupts per second. ben > > > - erik > >
