Help Me !! I need know where the library mathXXXX.library look for 68881, because we want to add a math coprocessor in our Amigas. If somebody have just made it, please, send me some information about it. Thank you... ... marco@alessia.dei.unipd.it or livio@alessia.dei.unipd.it P.S. If you can't reach us use this addresses: marco%alessia.dei.unipd.it@mcsun.eu.net livio%alessia.dei.unipd.it@mcsun.eu.net

If it exists when it opens and initializes it looks at various fields in the resource structure. One of those fields contains a pointer to the 68881/68882 base io addresses if the resource is for a 68881/68882. The vendor of the 68881/68882 should be providing the autoconfig software to set this up as well as the code that saves and restores the 68881/68882 registers for task switching. -- Dale Luck GfxBase/Boing, Inc. {uunet!cbmvax|pyramid}!amiga!boing!dale

I would like to do something similar, but unfortunately, I haven't been able to find any documentation on how to do it.
