 First, follow the directions above in regard to removing the case to gain access to the TOS chips. There are two methods to add multiple TOS's to your machine.
-====Method 1====
+====Method 1 (Easy)====
 The simplest method if you already have your 32 pin TOS chips in your machine and some 32 pin TOS 2.06 eproms in your hand is to piggyback them on top of the the existing TOS 1.6x chips and connect them to a small toggle switch so that you can flip between the two versions.

-====Method 2====
+====Method 2 (Advanced)====
 This method involves effectively burning two versions of TOS to a single chip. By using an eprom that is twice the size of a normal TOS eprom, you can divide it into two banks, and program it with 2 different TOS instead of one. Banks are selected by connecting a switch that either feeds ground, or +5v, to the highest adress pin of the eprom, which effectively selects which part of the eprom that you want to use. The principle easily adapts to even larger eproms, in theory letting you choose between 4 or even as many as 8 different versions of TOS. Even though it is of little interest to most people.

 ==Multi TOS==
-Multi TOS is a very useful upgrade that let you have 2 (or more) different TOS's in your STE. This is useful because TOS 2.06 is not compatible with all software written with TOS 1.6x in mind. With a simple switch you can easily switch between them and always be able to run your favourite game or application.
