I think some work (remember a thread about memory and proliant server).
And I read (in my V100 manual) that you can use either EEC or non-EEC (but
not both and have to switch a jumper) - if I understood it well =3D)

Maybe I should try the target configuration on some old Celeron 500MHz
I own and see if such a frequency is enough... :)

no :( I couldn't find specs such as IDE bus speed, ...

ok
in fact, the "package" of those workstation is not the same.
the SB150 has a 80Go disk and USB keyboard when the SB100 has none (disk&ke=
yboard),
but as I have a 120Go/8Mo_cache lying there, it'll fit in whichever I buy :)

yeah - looked like the same video card (PGX64), PCI slot number and DVD dri=
ve.
thanks for the notes !
