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

(rest deleted) Hi, I think your problem may be that your blocksize spec for hd3 in the /etc/setup_root should be 512 instead of 2016. Otherwise, when minix tries to load the ram disk off /dev/hd3, it tries to load 2016 blocks and you haven't got that much memory ! Try: /etc/setup_root /dev/hd3 512 113903 12500 512 22680 (I also set my dos partition size to 0. It seems to work). I am not too sure without looking, whether /etc/setup_root performs the mkfs for /dev/hd3; if it doesn't, then you have to "mkfs /dev/hd3 512" beforehand, to make a 512k filesystem on /dev/hd3. I am sorry but I don't any info on mx386; I am about to try it myself ! -- Martin Grundy | email: grundy@rtf.bt.co.uk British Telecom Customer Systems | Hyperion House | phone: +44 273 762102 96-99 Queens Road | fax: +44 273 722038 or Brighton BN1 3XF. | +44 273 762071 (netfax)
