[B2-devel] Problems mounting MacOS disks under Linux, for SheepShaver

[Andrew L. <and...@in...>]

Hi,

Having downloaded, compiled, installed and configured 
SheepShaver-2.3-0.20060514.1  (my configuration is shown at the end of this 
e-mail), on my linux box (Mandriva 2007, KDE 3.5.4, Core2 Duo Processor, 
Kernel 2.6.17.13), I find I'm unable to install either MacOS 8.5 (purchased 
recently off ebay), or my original MacOS 7.5.3 disk (purchased with my Mac 
Performa some years ago) onto the 'hardfile' created under the SheepShaver 
Settings window.

I think this stems from a 'mounting' problem, since MacOS 8.1 mounts and 
begins to load under SheepShaver, whereas MacOS 7.5.3 & MacOS 8.5 neither 
mount nor begin to load under SheepShaver.

Here's what happens using the MacOS 8.1 disk . . . . . 

   [root@internode Unix]# mount -t hfs /dev/hda /mnt/cdrom
   mount: block device /dev/hda is write-protected, mounting read-only
   [root@internode Unix]# exit

... and then I open SheepShaver Settings window from within a shell using 
(using the options shown at the end of this e-mail).
   [root@internode src]# ./Unix/SheepShaver
   SheepShaver V2.3-Pre (May 17 2007) by Christian Bauer and Mar"c" Hellwig
    
Then When I then click 'Start', an alert window appears . . . . 
  SheepShaver Warning:
  Cannot open /dev/sheep_net (Permission denied). Ethernet will not be 
available.

Upon clicking 'OK', the SheepShaver window opens, initially showing the MacOS 
window and "Welcome to Mac . . " (if I have the MacOS8.1 disk in the the 
drive), but then crashes (closes) SheepShaver instantly.  At this point, the 
shell output, as root user, is:
    [root@localhost src]$ ./Unix/SheepShaver
    SheepShaver V2.3-Pre (May 17 2007) by Christian Bauer and Mar"c" Hellwig
    Reading ROM file...
    Using /dev/dsp audio output
    Detected CPU features: MMX SSE SSE2 SSE3 SSE4
    PowerPC CPU emulator by Gwenole Beauchesne
    Illegal instruction at 40df1200, opcode = 00000000
    [root@localhost src]$

If I repeat the above procedure but use my MacOS8.5 Disk (after first 
switching to the Mac OS ROM file that I've transferred to the computer via 
network connection to my old Mac), I find the MacOS 8.5 disk will not even 
mount.

  [root@internode Unix]# mount -t hfs /dev/hda /mnt/cdrom
  mount: block device /dev/hda is write-protected, mounting read-only
  mount: wrong fs type, bad option, bad superblock on /dev/hda,
       missing codepage or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

    [root@internode Unix]# 
    hfs: unable to set blocksize to 512
    hfs: can't find a HFS filesystem on dev hda.

If I ignore my inability to mount the MacOS8.5 CDROM, and simply start 
SheepShaver, (changing the memory to settings to use the Mac OS ROM that I 
copied from the MacOS8.5 disk, over a network connection), then I just get a 
black (empty) SheepShaver window, and nothing happening (no Mac icons, 
no "Welcome to Mac . . ." . . . . just nothing at all).  
Shell output is:

   SheepShaver V2.3-Pre (May 17 2007) by Christian Bauer and Mar"c" Hellwig
   Reading ROM file...
   Using /dev/dsp audio output
   Detected CPU features: MMX SSE SSE2 SSE3 SSE4
   PowerPC CPU emulator by Gwenole Beauchesne

Now, I don't think that this is a problem with the MacOS 7.5.3 & MacOS 8.5 
disks being damaged, since if I use the 'hmount' command from shell with the 
MacOS8.5 disk in the drive (hmount /dev/hda), I get the following:

   [andrew@internode Unix]$ hmount /dev/hda
   /dev/hda: contains 1 HFS partition
   Volume name is "Mac OS 8.5" (locked)
   Volume was created on Mon Nov 24 09:01:00 1997
   Volume was last modified on Tue Sep 29 10:18:21 1998
   Volume has 111272448 bytes free

If I do the same thing on the MacOS8.1 disk, I get the following shell output:

   [andrew@internode Unix]$ hmount /dev/hda
   /dev/hda: contains 1 HFS partition
   Volume name is "OS 8.1 Install" (locked)
   Volume was created on Thu Jul 20 13:19:44 2000
   Volume was last modified on Mon Jul 24 15:40:57 2000
   Volume has 0 bytes free


On another tangent, it seems I need to sort out what's wrong with the ROM file 
I created on my old PowerPC Macintosh Performa 5600, since, if I enter the 
directory containing my ROM file and do the check described at 
http://gwenole.beauchesne.info/en/projects/sheepshaver/help/faq, then I 
get . . . .

    [root@internode macintosh_emulation]# strings 'Mac OS ROM' | grep "Boot "
    MacOS: Boot Failure!  (0xF3C481F6)
    [root@internode macintosh_emulation]#


So, two questions.

1. Is there a package I need to install in order to be able to correctly mount 
my Original MacOS disks (Versions 7.5.3 & 8.5) ?

2. Am I wrong to believe that a ROM generated by TomeViewer in a Macintosh 
Performa 5600 will be any good at all ?

I'd value any assistance you could provide to help me get going with 
SheepShaver.  

Cheers,

Andrew
