I have 2 Rev. D RAMFasts. Can someone please tell me the difference
between the later ROM revisions? What is the difference between 3.01F
and 3.01-EZ? My EZ appears to have a different main chip (Zilog) than my
other? Can someone shed some light on this?

Thanks!


The 3.01EZ ROM has a bug in it which is why it was followed up by the
3.01F ROM.  The bug is, if I remember correctly one that causes
complete data loss with the drive and should not be used. (It seems to
me there was one function that caused this in particular but I dont
have my notes in front of me.)



So, 3.01F *supersedes* -EZ, regardless of model controller chip?
