First of all you need to put c:cyberpatcher >NIL: early in you
s:startup-sequence to make sure that non-060 opcodes are emulated in
virtually everything you run on your machine.
Then make sure the 060 libraries are installed correctly, I won't go
through this here but you need to get the archive off aminet (the latest
version is biz/p5/68060-V44_3.lha) and follow the installation instructions
in the archive to the letter. Read the supplied instuctions carefully and
you can't go wrong.
No, get FastExec off aminet (util/boot/FastExec29.lha) and set this up,
again in s:startup-sequence, to relocate your exec.library in FAST memory
(I wouldn't bother relocating SSP or expansion.library as this can upset
many programs). IIRC this mod made the biggest difference to my 060 speed.
As for you CD copy speed, as you are talking of 600MB of data..
24x CD drive (max data read) 3.6MB/s (150k/sx24)
Gives us 600MB/3.5MB = 166.7 seconds to copy (max) = 2.8 minutes
My SCSI (Blizzard IV) writes to my HD at about 6MB/s, so the copy'd should
be done in less than 5 minutes by my reckoning.
You must make sure that the mask values for your HD and CD are right
though, internal HD should be:
Mask: 0xfffffffc
Maxtransfer: 0xfffe00 (if you drive will take it, most modern ones will)
If your CD is on a squirrel SCSI, I don't know what the mask should be as I
don't know what memory area the PCMCIA bus can access (If it's CHIP only
you'll get a massive speed hit) but it should ALWAYS end in c for the amiga
to lonword align the data in memory (the processor likes longword aligned
data best).
If it's on the Powerflyer I'd reckon your mountlist for the flyer should
have a:
Mask=0xfffffffc
MaxTransfer0oxfffe00
in it!
If you had the Blizzard SCSI you'd get MUCH better performance than using
the Squirrel, and probably better than the powerflyer too.
Hope this helps,
Kev
