Hello,

	I have a 486sx25 ISA machine with Pheonix BIOS.  Currently I have  
8 megabytes of RAM installed via eight 1 MG SIMMS on the motherboard: ie.  
both banks are full, and there is no space for more SIMMS.  I am thinking  
of running OS2 on my machine and Possibly Linux with X windows, and I know  
that more RAM would be helpful.  However with SIMMS, the only solution I  
can see is to sell my 8 Megs for about $180, and by 4 4mg SIMMS for about  
$400 used. Apart from the fact that I can't afford the price right now,  
the entire process of selling RAM and buying it used probably means that  
the machine might be down for a number of days which I would rather  
avoid...

So my question is, do the AT RAM boards that plug into a free slot work  
well with a 486 ISA machine. I have seen some being sold used for about  
$90 with 4 Mg with space for another 4Mg's.  If these boards do work, how  
do they do it?  Is a device driver needed, or will the BIOS pickup the  
extra RAM as it does with the SIMMS on the mother board? I know that the  
ISA expansions slots are 16-bits and 486 SIMM memory is 32 bits, so  
probably all of this is just wishful thinking... However any help is truly  
appreciated.

-Eric
