I had hoped things improved :( when I was having problems with my mvsas bas= ed=20 card, there was someone making commits to the code from marvell and I got s= ome=20 kind of response once or twice, but stopped replying and problems were neve= r=20 fixed. I however haven't had any real issues with my dirt cheap ($50-100) IBM M101= 5=20 cards (I have three). A lot of people have had good results with them.=20 Technically its a 9220, which is quite similar to a 9211, but has some slig= ht=20 differences. =2D-=20 Thomas Fjellstrom thomas@fjellstrom.ca
