    I am about to install Parallels on my Mac Pro but I am having
    some initial problems.

    I selected CUSTOM INSTALL because it allows me to specify
    how much memory and hard drive space I want to dedicate
    to Parallels.

    1. It asks how much memory (RAM) i want for my virtual machine.
    I want 2GB (I have a 4GB computer). What does this translate to
    in MB? I maxxed it out at 1500MB. Is this correct?

    2. It asks if I want to CREATE A NEW HARD DISK IMAGE. I tell
    it yes, and I am guessing this is correct.

    3. SPECIFY SIZE OF VIRTUAL DISK. I want 250GB (I have a 500GB
    drive) dedicated to Parallels. What is the MB equivalent?

    4. At this point, it will only let me select BRIDGED ETHERNET or
    NETWORKING IS NOT REQUIRED. The other two choices are
    grayed out. I want to use my Mac ethernet connection for my
    Internet and use AIRPORT EXPRESS for my wireless printer. What
    should I use here?

    5. Next step gives me choice of DEFAULT ADAPTER or a list
    of two other adapters + Airport/Wireless adapter. Again, I
    connect to the Internet via Ethernet and Airport is used solely
    for the wireless printer.

    Help would be greatly appreciated!

    I'm guessing you want windows...

    You don't need custom install, select regular and you can later choose RAM specification. Let it use the maximum RAM. You can make it only use up the HD space you need, so it grows with whatever you put on it. Use bridged connection, it connects to the connection your OSX is on at the time...

    I appreciate the help.

    I am assuming you are saying to install WINDOWS EXPRESS
    and let Parallels do it all.


    After Vista install is done and I get around to allocating certain
    preferences, what are the settings to tell Parallels....

    I want 2GB ram (out of my 4GB hard drive)
    I want 250GB hard drive space (out of 500GB hard drive)

    Everything is in MB so it kind of throws me off.

    More problems...

    I installed Parallels according to EXPRESS INSTALL.

    Vista installed fine.

    Got as far as installing my Internet Security and Antivirus.

    Vista had problems rebooting. It just sat there at the load
    screen. So, I went into tools and put in the maximum memory

    When I tried to start Parallels I got this message:

    "Unable to allocate virtual machine memory!

    This error may occur mostly if there is no enough free
    disk space available on the physical disk to allocate virtual
    machine paging file. Try to clean up the physical disk.
    If it doesn't help, try to re-install Parallels desktop."

    Can someone kindly instruct me how to max out all
    the necessary VIDEO and MEMORY areas effectively if
    I want 2GB RAM and 250GB hard drive space for Parallels?

    Note: I tried putting 250,000MB in the Hard Disk settings
    but it was much too high a setting for Parallels to handle.
    It will not let me put in anything above 128,000MB. On
    the Memory end, it will not let me go above 1500MB.

    Thank You!
