I just got ahold of an old compaq proliant 1000, and i have the oppourtunity to upgrade it to a proliant 4000 with 4 166mhz processors. :D However, sometime last year i heard that the architecture of the 4000 makes it impossible to use all four processors under linux. :mad:
i found this reference in some archive:
The problem is that the PL4500 is an entirely EISA based

> Table Mapped." In this case, even if there was a choice for
> APIC mode on
> the PL4500, it would have only 1 selection: "EISA Mapped" Linux is
> currently unable to use processors under this mapping scheme

does anybody know if this may have been resolved in newer kernels like 2.4?
