It's more likely the result of shoddy 3Com engineering, or that the ep driver is still not very good (at least compared to fxp..). My 3C574BT never seems to get faster than 1.5MB/sec on half-duplex 100BaseTX with no LAN traffic. On that note, my 3C905B-TX doesn't get faster than 4.5-5MB/sec on the same LAN, half-dup 100BaseTX, to an identical card. The first may also be the result of the fact that the PC-Card bus isn't really capable of handling 100BaseTX data thoroughput. Which is mostly why we need CardBus code in FreeBSD. :-) > There's just one other problem that I'm not getting a hold of... > Card inserted, slot 0 > card0: assign ep0 iobase 0x240 irq 3 flags 0x1 > ep0: No connectors or MII. > ep0: [*UTP*] address 00:00:86:50:43:1f > > It says ep0: No connectors or MII. but works anyway.

P.S. No offense intended about the ep driver comment. P.P.S. Besides, I'm not sure what the protocol bandwidth limit for half-duplex 100BaseTX is anyway... but I had the vague feeling it would let me push through more than a measly 4MB/sec. ;P To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
