I have been trying to build 2 prologs with djgpp. CLPR (from IBM research) and
SWI.  Got both built ok on my 386 clone...has 60 meg drive and 4 meg of 
memory (2 real and 2 for cache).
Problem is...I am trying to also build on my IBM 386SX laptop.  It has a 16mhz
clock and 60 meg drive and 2 meg of memory (extended it says)...
Trouble is, I moved over my compiler et al and removed the caching, but
have had nothing but problems...
Twice it hung compiling...once in CLPR and once in SWI, and both times 
caused a hard-disk failure that required replacing the hard drive! (a 1790
failure to be exact...even the reference disk wouldn't boot)...
In any case, it is now on it's third hard drive (it is under warantee luckily)..

-- 
Last nite, I was able to at least compile many of the mods in these prologs, but
some still hung the machine...sometimes it gave a segmentation violation at
0x9 or 0xa and an exception 14 at exp=59531...
Note that none of this happens on my clone!...
The clone is dos 3.3 and the laptop is 5.0...
They both should have 2meg of effective memory (extended)...
It seems like the failures are only on the larger compiles...I thought that
djgpp had no minimum memory requirement tho...
In any case, the latest is that last nite after one of the failures, I tried
to reboot and it told me "missing operating system"...
I tried to re-install dos etc but it insists now the hardisk is only 1 meg...
fdisk etc still only think it's one meg...ran the ibm ref disk and tested all,
reset all etc ..still only 1 meg...have a call into ibm service for this one 
but...
Any ideas on what is causing all this flakiness on this laptop?
Do I need any special extended memory driver?
What I haven't had a chance to do yet it redo the laptop with dos 3.3 and
then try it...tho I would think 5.0 would be superior, but who knows...
Is anyone out there building ok with dos 5.0?
thanx
cheers
