[net.micro.mac] ramstart 1.21 patches for HFS

jimb@amdcad.UUCP (Jim Budler) (04/01/86)

I posted ramstart 1.21 to the net a while ago, and stated that it could 
be used, but not autobooted on a Mac+.  I made the same statement on
Compuserve and received the following in reply:

Jim (and All): Here are the changes to make RamStart compatible with HFS.
These changes are confirmed on version 1.22, and I'm fairly confident that the
patches will be the same for version 1.21.  Use Fedit as follows:

[It turns out there WAS a difference between 1.21 and 1.22.  After several
interchanges came the following:]

OK.  I broke down and downloaded RamStart 1.21, and here are the applicable
patches:
 
   In sector $0C, offset $B4, replace 4EBA 0682
                                 with 4E71 4E71
 
   In sector $0D, offset $17A, replace 6700 0012 006E 8000
                                  with 6000 0012 006E 8000
 
If you're using a hard disk, you may need to apply the following patch (I had
to use it for both the Corvus and the Warp Nine):
 
   In sector $06, offset $190, replace 41FA 0388
                                  with 6000 000C
 
The symptom for this last problem is a message "can't find our drive #".
 
I'm not sure why you got this message even with floppies, but I consider it
safe to go ahead and apply this last patch anyway.
 
Another note (for those who didn't see the 1.22 patches):  RamStart uses a DRVR
10, which is a problem if you're using AppleTalk.  To get around this, pick a
driver number which isn't being used in your system file, and use ResEdit to
change the DRVR number in RamStart (I used 11 on my system).
