32 bit compatability 4.x 64 bit



Hello,

I have a requirement to arrange for the install of RH 4.5 64 bit so
that 32 bit applications will happily run.
I managed to determine by googling that 3 package groups need to be
installed
* Legacy, Compatibility ARCH Development Support 8/8
* Legacy Software Development 5/5
* Compatibility ARCH Development Support 191/191

Now I have been asked to identify which specific packages these are
<sigh>.
But I dont know how to find this out.

Someone must know - please tell me!

TIA

Ton
