I've got no problem with that, of course. I guess I was thinking pessimistic thoughts about finding a fix for this for .22

So what I'm seeing is a failure at 100MHz operation. Is there any way to put the Promise into 66MHz mode (other than using a drive that runs no faster)? Because at this point I don't have any practical way to rule out the possibility that the cable/drive are what's marginal at 100MHz; aside from the Promise, I don't have anything faster than a UDMA66 card (which works fine with them).
I also managed to find a useful non-broken link on ASUS's web site and found that they had snuck out a BIOS update later than the latest I had previously known of, and it did include a minor change in the Promise BIOS (from 2.01 build 19 to build 35). Made no difference, though: the 50MB copy still failed as usual with 22-rc2.
