OpenServer 5.0.6 on Netfinity 3500 M20

Has anybody installed SCO OpenServer 5.0.6 on a Netfinity 3500 M20 yet? What about on other Netfinity products?

Are there any BIOS upgrades needed?

I would like to be informed ahead of time of any potential install or runtime problems with 5.0.6 before going ahead and ordering it. If anyone recommends 5.0.5 at this point instead, please let me know.

(This is for one of our “not so nice” customers and having to deal with them on a daily basis because of huge OS problems is not an option for me or my sanity)

Thank you so much
