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
