You should never listen to Zick. 53c710 is always part of Lasi on PA machines. There's a discrete 53c700 on pre-Lasi machines. There is never a 53c710 behind Dino. Dino has a serial port, a ps/2 port, and a pci host bridge. > * most probably the pb is well in sg list management in ccio (afaik > not used by dino) Wrong. sg list management is used by PCI devices behind Dino as well as by GSC devices. _______________________________________________ parisc-linux mailing list parisc-linux@lists.parisc-linux.org http://lists.parisc-linux.org/mailman/listinfo/parisc-linux
