Re: Urgent Help needed Please: Mounting a cdrom device post successful install of AD X86 Ver 8.0

First of all, drive number assignments in the /dev/ directory are dynamic (unless this has changed with v. 8.0?). So a GNU/Linux /dev/hdb is not going to translate to a specific drive number in Darwin.

Second, you need to specify which partition you're trying to mount.

Here's what I'd recommend:

Do an 'ls /dev/disk*' before putting the CD in your drive. Note the drives listed (drives are listed in the format 'diskXsY', where X is the drive number and Y is the partition number). Now put the CD in and do an 'ls /dev/disk*' - you should see one more drive appear. Now just mount the preferred partition using the mount_cd9660 command. For example, it may be 'mount_cd9660 /dev/disk1s2 /Volumes/cdrom'.

My guess, judging from the drives you listed, is that your CDROM device will be /dev/disk2 - assuming that the other four drives are completely inaccessible from Darwin. If they're accessible from Darwin, it'll probably be /dev/disk6. If you boot with a CD in the drive, the device would probably be /dev/disk1.

Hi everyone,
Could someone look at our config and offer an urgent solution.... PLEASE !

Our FIRST IDE ATA COMPLIANT DRIVE (or Primary Master) IS A 40Gig WD. From which we Multi Boot a text based Dos, also other *nix (Linux) OS's, Win2k Pro etc.

Our SECOND IDE DEVICE (or Primary Slave)IS AN LG CDROM / DVD Super Multi Combo Device.

Our THIRD IDE ATA COMPLIANT DRIVE (or Secondary Master) IS an 80Gig WD.

From which we Boot Apple Darwin Version 8.0.0 useing our Gigabyte CMOS to shift it ^^^ UP to first place in our Drive Array (NON RAID). It then always boots to the AD v8.0 Boot Prompt with out any problems.

The other four HDD's are all SATA Drives, which are on seperate controllers, and are not relivant to these matters at all.

Our problem is in getting our cdrom / dvd combo to mount,,,, even in read only mode !!!!

Our CDROM is likely to be called or known as /dev/hdb in linux
In Darwin possibly rdisk1s0

--------------------------------------------------------------------------
REMEMBER : Our LG CDROM / DVD Super Multi Device Drive is the 2nd (Second) Physical ATA / ATAPI Device at all times.
--------------------------------------------------------------------------

Unlike Open Darwin which seems to have a directory and or folder called /Volumes "NO" such Directory is found with an ls at the root prompt, where Apple Darwin Version 8.0.0 is concerned !!!

BUT a .vol directory is,,,,,, it only seems to contain a rather long number (probably).....maybe the Apple Darwin Host Drive itself - the drive we installed Apple Darwin onto at original install time .... perhaps ?

So I guess we have the following questions,

1.) Is there a particular already created directory post install where our cdrom can be at least read from and copied from.

2.) Where do we navigate to from the root prompt.

IF NOT..........

3.) How do we mount /automount our CDROM /DVD DEVICE at boot or post boot.

4.) And to save another similar post how do we "UNMOUNT" the CDROM /DVD post booting.

We have tried creating a folder and sub folder directly from root " / " called /Volumes/cdrom

then used mount_cd9660 /Volumes/cdrom

mount mount_cd9660 /Volumes/cdrom

All to no avail, common errors state that basically the file ando or folder do not exist.

What's the closely guarded secret about getting cdroms /dvd's to mount in Apple Darwin ???

In most flavours of Linux it is as simple as falling off a long, "IF" you have to manually crank up a cdrom / dvd into life, which has been a rare thing with them over the last few years. Some lines of text in fstab an the creation of a folder and or sub folder under /mnt have you accessing your drive very quickly.

Your help from those using Open Darwin x86 version 8.0 would be appreciated.

Thanks in advance for your help !

By the way the CDROM / DVD works fine and is able to be fully used with all other OS's on this x86 PC !!!!!

cheers,
kelly.
