Here is the do-it.  Select it all and execute.  Thereafter you should be able to update, and this will bring in 8 updates, the last of which will offer to advance your update version to 2.4.  Answer yes.

If you are not Squeak-connected to the network, there is yet another way.
Go to the Squeak 2.4 folder on the UIUC server, and fetch the entire folder named
	24to24a.cs
being certain that all files are retrieved in raw binary mode.  Then fileIn all those
files in order, and you will have a 2.4a-equivalent image.

Carry on.
