3196.0. "Note for Problems with A590" by CSC32::K_APPLEMAN () Fri Dec 08 1989 18:32

    I would like to start a note concerning bugs and incompatible programs
    on Amiga 500's with an A590 hard drive attached.  I just put one on
    and, wouldn't you know it, I stat hearing about several programs that
    won't run properly in my configuration.  I think a list of those
    programs would be helpful for anyone considering purchase of this 
    product.  
    
    Also, any info on what is causing these problems would be appreciated.
    i.e. Is it bugs in the A590 or in the programs.
    
    Known problems so far:
    
    Virusx version 4.0
    	Guru's every time you run it.
    
    NewTek Demoreel 3
    	Strange graphics problems
    
    These 2 problems are referenced from previous notes. 
    
    There may also be a problem with Falcon from Spectrum Holobyte.  I
    haven't confirmed it yet, but after putting it on hard drive and
    clicking the icon, it loads then exits right back to the workbench.  I
    haven't tried loading it from 3.5 disk again since the A590 was installed,
    but will update this note as soon as I do.
    
    Any others?
    
    By the way, my configuration is 1 meg memory and 0k on A590.  I have
    1 meg for the A590 coming from Merical in Ohio soon.  Will see if this 
    changes any problems.  Falcon problem could be due to lack of memory.

3196.1Platium Scribble Guru's with A590CSC32::K_APPLEMANSun Dec 10 1989 20:1412
    Platinum Scribble!
    
    This is a confirmed probm.  Platinum Scribble guru's when trying to
    open an old file or when trying to change the default directory.  It
    will occur even if the original disks are booted from the floppies. 
    Disconnecting the A590 solves the problem The original Scribble! works
    just fine.  Will give MSS a call and see if they know of this and have
    a patch.
    
    Also, on the NewTek Demo, mine works fine with the A590 connected. 
    Have also gotten Falcon to start, but it is flakey.  Still
    investigating that one.
3196.2Fix for Platinum and VirusxCSC32::K_APPLEMANMon Dec 11 1989 22:3941
    Got a fix for the Platinum Scribble bug and for VirusX.  This comes
    from the Amiga_SYS note which contains the amiga.sys notes from usenet. 
    The original author is Andy Finkel of Commodore.  Apparently, the
    problem is that certain programs make an illegal (according to Andy)
    reference to location 0.  The AutoBoot of the A590 changes location 0
    to GDOS (whatever that is or does).  Programs that use location 0 then
    guru for whatever reason.
    
    The fix is simple enough but leaves some questions in my mind.  First
    the fix, then the questions.
    
    	1.  Boot the A590 Install Floppy
    	2.  Click on the HDtoolBox
    	3.  Click on the Partition Drive gadget
    	4.  Click on the Advanced Options gadget
    	5.  Click on Add/Update File Systems
    	6.  Click on Update FileSystem
    	7.  Give it a new version number but otherwise leave it alone.
    	    (apparently it doesn't matter what version you give it.)
    	8.  Click on OK then click on OK on the Partition page
    	9.  Get back to the main menu, then click on Save Changes to Drive
       10.  Repeat the above process for each partition on the drive.
       11.  Turn system off and reboot from the hard drive.
    
    I have done the above procedure and it cured my problems with both
    programs.  My question is: What exactly does simply giving the
    filesystem a new version number do?  It doesn't actually update the
    filesystem, nor are there other versions of the FileSystem in the l:
    library that it loads.  It sure sounds like a bug in FastFileSystem to
    me.
    
    Anyway, I am glad it is fixed.  Let's leave this note active anyway
    just in case some programs are found that have problems and can't be
    fixed with the procedure.
    
    Also, there is a note on Amiga_Sys, 2026.8, concerning disk performance
    of the stock XT drive and a SCSI CSC Wren III drive.  Makes interesting
    reading.  One item of interest is that adding more buffers on the stock
    XT drive above about 64 doesn't seem to help i/o throughput much.  This
    info could help you optimize your buffers.
