A few questions, posted on my wife's behalf, so that she feels safe to
talk to me again:

1. Has anyone got an update to this problem which I didn't have on a
386SX/16, but is only too obvious on a 486DX2/66?

2. Is it only 386BSD, or does NetBSD have this problem as well?

3. And does anyone have a WDCDELAY-patched kernel I can ftp from
somewhere?

4. Isn't this the same problem as the "can't build GENERICISA" thread?

Anyone?
