Hi,

        I have installed minix 1.5 on a Zenith Z386/25 with 150MB hard drive
and 640K + 1024 K entended memory. My partation 3 ( approx 2 MB) contains the
ram disk image while partition 2 is for the rest of the stuff.
        I used the command
/etc/setup_root /dev/hd3 512 113903 12500 2016 22680
                          |    |      |    |     |
                         ram   |    minix  |    minix - (for future use!)
 tried other sizes too <--|   dos        ram image

        for creating root file system.
On rebooting the system, I am getting a flashing error message "Memory manager
panic: not enough memory.  Automatic reboot." (or something like this).
        I have tried different ram size but had no success. I even tried minix
on a PC with 640k with ram size varing from 150k to 300k but always got the
same error here also.
        Any suggestion as where I am goofing up.

Very soon my 386 would be upgraded to 16MB of Ram and I am then thinking of
installing Bruce's 386 version. What I would like to know is what are the
benifits of having the 386 version ?? Does it have

1. Support for paging or swapping.
2. Stack overflow detection.
3 Or does it takes advantage of any other 386 hardware features like any use of
  4 layers of protection offered by 386, use of multitasking hardware, etc.

        Can someone please summerize the features of Bruce's 386 minix; and
finally, are there any other seperate 386 modifications that would add the
above features.

thanks for the help
