Hi folks, I have followed this thread for a while now, and I just thought that I would share my observation of my 3Com 509(b?) Card. I had put this card in a 486/33 Mhz, and it is now in a 586-133 Mhz (I forgot who made these chips), and in both cases I was able to make transfers of up to 100 Kb/s. What is even stranger is the fact that I was running this under FreeBSD 2.1.0-release (and later current of that period). Subsequently, although I know very little about hardware. I find it hard to understand how the card would work, if the card was misconfigured. I say this because I have always done ftp installs, and because the interupt that my 3 Com card is using is not the default one the kernel expects (Some silly conflict). This means that if I should forget to tell the kernel about it with the -c flag, that the probes will not even find the card. Or maybe I did something else, that is equally dumb. Furthermore, I do not think that it is PnP that is causing his problems either. When my card was put in PnP mode by Win95 (no flames please, I use it to learn how to use the visual compilers), FreeBSD seemed to be unable to use the card. On the other hand, with PnP disabled, it worked a charm. :) Ftp'ing the entire OS from FreeFall, even though we go through the "friendly" SprintLink, still managed transfers between 50-80 KB/s. So I think something else is wrong. Maybe operator error ;). Cause it seems to work very well for me. I guess I will find out when I get a another HDD soon, as I plan to play with Linux, as well as FreeBSD on the 586, with the 3Com card. What do you guys think would be a good benchmark ;) ??? In conclusion, how do you get transfer > 1000 KB/s ??? I have never seen anything over 150 KB/s. Although, I have to admit that do not connect to sites that are on the same ethernet segment, and that all the dormitories (I think), goes trough a Cisco router (don't know the model). Otherwise, I just want to say a big thank you to all the developers for bring me a wanderful learning tool. :) +---------------+----------------------------+---------------+ | Tam Weng Seng | May the source be with you | Tan Yongcheng | +---------------+----------------------------+---------------+
