[comp.sys.ibm.pc.hardware] Replacing motherboard inquiry. Help?

moe@milton.u.washington.edu (Joe Shippert) (06/03/91)

I've been thinking of replaceing my 80286-12 with one of those slick 386
motherboards. I've taken my whole computer apart before and added floppy
and hard drives all sorts of cards, memory upgrades and etc. but what all
is involved in replacing the whole motherboard? Where is a good place to
get motherboards and which boards are considered better? Worse? Thanks
for your help.

I like the AMI Mark III.  This comes in 25 or 33 Mhz versions, supports
upto 64Meg on the board using 4Meg simms, has 64K cache, and best of all
allows you to upgrade to a '486 based system with a plug in daughter
card.  The board size is a mini-at size and should fit your '286
chassis really well.  It has an AMI bios and runs windows, OS/2 (1.3 and 2.0)
and about any thing else I've thrown at it.  It cost around $900 with
4megs.

Another vote for AMI here.  And don't worry too much about the difficulty
of swapping motherboards.  Just be careful about static electricity, protect
all of your cards and the motherboard from physical damage, and keep track of
where all of your wires plug in.  With care, your motherboard swap can be a 
piece of cake.
