Of all the gin joints in all the towns in all the world, Vallo Kallaste had to walk into mine and say: > Edwin Culp <eculp@webwizard.org.mx> wrote: > > > Anybody tried it with the 3c595, that poor folks like us might still have? > > > > Thanks > > *** > > I can try. About what are you interested ? The xl driver is for 3c90x cards only: this includes the 3c900 and 3c905 "boomerang" adapters and the 3c905B "cyclone" adapters. The 3c59x cards are based on the "vortex" chipset, which actually does have a DMA mechanism but not the same as the "boomerang" and "cyclone" chips. The "boomerang" chips happened to work with the vx driver because 3Com maintained support for the old PIO packet transfer mechanism that the vx driver uses. But starting with the 3c905B, the PIO mechanism was dropped and now bus-master DMA is required. Since all 3c90x cards support the same DMA interface, I decided to split out all of the 3c90x support from the vx driver. The vx driver is still used for the 3c59x PCI cards; I only turned off support in the vx driver for the Etherlink XL PCI cards, not the Etherlink III PCI cards. -Bill > > Vallo Kallaste > vallo@matti.ee > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-current" in the body of the message > > -- ============================================================================= -Bill Paul (212) 854-6020 | System Manager, Master of Unix-Fu Work: wpaul@ctr.columbia.edu | Center for Telecommunications Research Home: wpaul@skynet.ctr.columbia.edu | Columbia University, New York City ============================================================================= "It is not I who am crazy; it is I who am mad!" - Ren Hoek, "Space Madness" ============================================================================= To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
