x x< > 3cr990 series "Typhoon" support (NEW) x x
la ayuda de la primera opcion:
x CONFIG_VORTEX: x
x x
x This option enables driver support for a large number of 10mbps and x
x 10/100mbps EISA, PCI and PCMCIA 3Com network cards: x
x x
x "Vortex" (Fast EtherLink 3c590/3c592/3c595/3c597) EISA and PCI x
x "Boomerang" (EtherLink XL 3c900 or 3c905) PCI x
x "Cyclone" (3c540/3c900/3c905/3c980/3c575/3c656) PCI and Cardbus x
x "Tornado" (3c905) PCI x
x "Hurricane" (3c555/3cSOHO) PCI x
x x
x If you have such a card, say Y and read the Ethernet-HOWTO, x
x available from <[url]http://www.tldp.org/docs.html#howto[/url]>. More x
x specific information is in x
x <file:Documentation/networking/vortex.txt> and in the comments at x
x the beginning of <file:drivers/net/3c59x.c>. x
y la segunda:
x CONFIG_TYPHOON: x
x x
x This option enables driver support for the 3cr990 series of cards: x
x x
x 3C990-TX, 3CR990-TX-95, 3CR990-TX-97, 3CR990-FX-95, 3CR990-FX-97, x
x 3CR990SVR, 3CR990SVR95, 3CR990SVR97, 3CR990-FX-95 Server, x
x 3CR990-FX-97 Server, 3C990B-TX-M, 3C990BSVR x
x x
x If you have a network (Ethernet) card of this type, say Y and read x
x the Ethernet-HOWTO, available from x
x <[url]http://www.tldp.org/docs.html#howto[/url]>. x
x x
x To compile this driver as a module, choose M here and read x
x <file:Documentation/networking/net-modules.txt>. The module x
x will be called typhoon. x
y casi te puedo asegurar que o es un modulo o es otro, lo que me extraña es que no te lo detecte el knoppix.
Saludos y suerte
