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

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

Hi,

My apologies for any confusion. In the original e-mail, I referred to a Mac=
=20
Performa 5600.  I should of course have said Performa 5260.  The corrected=
=20
version of the e-mail I sent a short time ago, is shown below . . . . . . .



Having downloaded, compiled, installed and configured=20
SheepShaver-2.3-0.20060514.1 =A0(my configuration is shown at the end of th=
is=20
e-mail), on my linux box (Mandriva 2007, KDE 3.5.4, Core2 Duo Processor,=20
Kernel 2.6.17.13), I find I'm unable to install either MacOS 8.5 (purchased=
=20
recently off ebay), or my original MacOS 7.5.3 disk (purchased with my Mac=
=20
Performa some years ago) onto the 'hardfile' created under the SheepShaver=
=20
Settings window.

I think this stems from a 'mounting' problem, since MacOS 8.1 mounts and=20
begins to load under SheepShaver, whereas MacOS 7.5.3 & MacOS 8.5 neither=20
mount nor begin to load under SheepShaver.

Here's what happens using the MacOS 8.1 disk . . . . .=20

=A0 =A0[root@internode Unix]# mount -t hfs /dev/hda /mnt/cdrom
=A0 =A0mount: block device /dev/hda is write-protected, mounting read-only
=A0 =A0[root@internode Unix]# exit

=2E.. and then I open SheepShaver Settings window from within a shell using=
=20
(using the options shown at the end of this e-mail).
=A0 =A0[root@internode src]# ./Unix/SheepShaver
=A0 =A0SheepShaver V2.3-Pre (May 17 2007) by Christian Bauer and Mar"c" Hel=
lwig
=A0 =A0=20
Then When I then click 'Start', an alert window appears . . . .=20
=A0 SheepShaver Warning:
=A0 Cannot open /dev/sheep_net (Permission denied). Ethernet will not be=20
available.

Upon clicking 'OK', the SheepShaver window opens, initially showing the Mac=
OS=20
window and "Welcome to Mac . . " (if I have the MacOS8.1 disk in the the=20
drive), but then crashes (closes) SheepShaver instantly. =A0At this point, =
the=20
shell output, as root user, is:
=A0 =A0 [root@localhost src]$ ./Unix/SheepShaver
=A0 =A0 SheepShaver V2.3-Pre (May 17 2007) by Christian Bauer and Mar"c" He=
llwig
=A0 =A0 Reading ROM file...
=A0 =A0 Using /dev/dsp audio output
=A0 =A0 Detected CPU features: MMX SSE SSE2 SSE3 SSE4
=A0 =A0 PowerPC CPU emulator by Gwenole Beauchesne
=A0 =A0 Illegal instruction at 40df1200, opcode =3D 00000000
=A0 =A0 [root@localhost src]$

If I repeat the above procedure but use my MacOS8.5 Disk (after first=20
switching to the Mac OS ROM file that I've transferred to the computer via=
=20
network connection to my old Mac), I find the MacOS 8.5 disk will not even=
=20
mount.

=A0 [root@internode Unix]# mount -t hfs /dev/hda /mnt/cdrom
=A0 mount: block device /dev/hda is write-protected, mounting read-only
=A0 mount: wrong fs type, bad option, bad superblock on /dev/hda,
=A0 =A0 =A0 =A0missing codepage or other error
=A0 =A0 =A0 =A0In some cases useful info is found in syslog - try
=A0 =A0 =A0 =A0dmesg | tail =A0or so

=A0 =A0 [root@internode Unix]#=20
=A0 =A0 hfs: unable to set blocksize to 512
=A0 =A0 hfs: can't find a HFS filesystem on dev hda.

If I ignore my inability to mount the MacOS8.5 CDROM, and simply start=20
SheepShaver, (changing the memory to settings to use the Mac OS ROM that I=
=20
copied from the MacOS8.5 disk, over a network connection), then I just get =
a=20
black (empty) SheepShaver window, and nothing happening (no Mac icons,=20
no "Welcome to Mac . . ." . . . . just nothing at all). =A0
Shell output is:

=A0 =A0SheepShaver V2.3-Pre (May 17 2007) by Christian Bauer and Mar"c" Hel=
lwig
=A0 =A0Reading ROM file...
=A0 =A0Using /dev/dsp audio output
=A0 =A0Detected CPU features: MMX SSE SSE2 SSE3 SSE4
=A0 =A0PowerPC CPU emulator by Gwenole Beauchesne

Now, I don't think that this is a problem with the MacOS 7.5.3 & MacOS 8.5=
=20
disks being damaged, since if I use the 'hmount' command from shell with th=
e=20
MacOS8.5 disk in the drive (hmount /dev/hda), I get the following:

=A0 =A0[andrew@internode Unix]$ hmount /dev/hda
=A0 =A0/dev/hda: contains 1 HFS partition
=A0 =A0Volume name is "Mac OS 8.5" (locked)
=A0 =A0Volume was created on Mon Nov 24 09:01:00 1997
=A0 =A0Volume was last modified on Tue Sep 29 10:18:21 1998
=A0 =A0Volume has 111272448 bytes free

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

=A0 =A0[andrew@internode Unix]$ hmount /dev/hda
=A0 =A0/dev/hda: contains 1 HFS partition
=A0 =A0Volume name is "OS 8.1 Install" (locked)
=A0 =A0Volume was created on Thu Jul 20 13:19:44 2000
=A0 =A0Volume was last modified on Mon Jul 24 15:40:57 2000
=A0 =A0Volume has 0 bytes free


On another tangent, it seems I need to sort out what's wrong with the ROM f=
ile=20
I created on my old PowerPC Macintosh Performa 5260, since, if I enter the=
=20
directory containing my ROM file and do the check described at=20
http://gwenole.beauchesne.info/en/projects/sheepshaver/help/faq, then I=20
get . . . .

=A0 =A0 [root@internode macintosh_emulation]# strings 'Mac OS ROM' | grep "=
Boot "
=A0 =A0 MacOS: Boot Failure! =A0(0xF3C481F6)
=A0 =A0 [root@internode macintosh_emulation]#


So, two questions.

1. Is there a package I need to install in order to be able to correctly mo=
unt=20
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=
=20
Performa 5260 will be any good at all ?

I'd value any assistance you could provide to help me get going with=20
SheepShaver. =A0

Cheers,

Andrew
