Your Dell 4550 ABSOLUTELY WILL accept two
1Gb memory sticks, for a total of 2Gb.

You do not need a BIOS update.

When the PC was built, there weren't 1Gb memory DIMMS available, so
the stated maximum capacity is 1Gb. However, I have had 2Gb
installed in my Dell 4550 for a year, and it's recognized by either
Windows XP or Linux (I dual boot).

Yet, this being said, you have to be careful. You need to install
what's known as "Low Density" memory, which consists of
128Mx64 bit chips on the DIMMS.

So, you need to find: 184-pin DDR, Non-ECC, Non-Registered, LOW
DENSITY PC-2700 RAM

DId I remember to say LOW DENSITY?
