 Nor did I yet, ok, he will be removed :-)

 704?  Oh, never heard of that one.  I now remember that I have access to
an old 601/75 IBM machine.  No idea if this one has OFW. I bet not.

 I did that testing. I had 8MB as a start, then upgraded to 32MB.

 Ok, will be removed.  I wasn't sure how OFW or your loader handles
non-contig memory situations.

 Iks, I forgot about that. I could be in need of that quite soon anyway :-)

 Damned, of curse I meant PPCP.  Maybe I shouldn't even start to mention
about PREP and CHRP at all, but always speak about PPCP and have a
definition about that somewhere.

 I bet it would run on any FirePower.

 Oh, and does NetBSD/powerpc run?

 Not *yet* - let me finish the FAQ.

 *Sic* This book is a very valuable source, pity that it is that expensive.

 A bad Search&Replace. Means MS-DOS or WinNT.

 And Linux for Be. Any pointer on that?

 They no longer are the same.  NTFS is able to access upto 4 Hexabyte,
whereas HPFS only can access 4GB.  Among other, smaller differences, this
is the most important.  I meant NTFS.

 No problem.  And I want to maintain it for a while at least.  If I cannot
help on working on the port, I may at least help you to do so in killing
all possible questions :-)

 What you may have guessed from the text and the errors - the FAQ is based
upon another FAQ.  I yet have to complete it to be dedicated to
