“Sun’s Solaris operating system is running on prototypes of
Intel’s upcoming 64-bit chips, becoming the last of the major
server computer operating systems to do so…”
“A version of Windows and Linux were demonstrated when Intel
unveiled the first Itanium samples in late August. HP said in
September that its version of Unix, called HP-UX, was running on
the Itanium prototype.”
“IBM had passed a similar milestone for its new operating system
about two weeks earlier, called Monterey-64. Monterey-64 is a
combined version of the Unix products from IBM, the Santa Cruz
Operation, and Sequent, a server maker IBM acquired.”
