Not yet. Next week is mostly holidays (there are three one-day
holidays in Taiwan that week, go figure), but if the guy is in, I'll
go up and try reattaching it. I need to reboot the system with a new
kernel anyway to see how the new aic7xxx stuff works, as well as
checking out support for his SB16 card and the CD-ROM attached to it.
Ah, just finished compiling... 10:55 for a kernel build. Over twice
as fast as my 486, *sigh* ...

The Pentium has twin Quantum Maverick 540's and my machine (with
the NCR controller) has a Quantum Empire 1080. I'll bring my drive up
to the Pentium and do another comparison. It is quite noticeably
slower for any heavy disk operations. Untarring the kernel source
dist and running config(8) are both noticeably faster on my 486.

*clap* *clap* *clap* :) He had bought Windows NT and was quite
disappointed with it. Then the Computing Center spent three days
installing Windows for Workgroups, mostly for naught. So one
afternoon of work to transform his PC into a real UNIX-breathing,
TCP/IP-speaking X11R6 workstation was nothing short of a miracle in
his eyes. ;-) Another CC support guy was up there with me, and he
was quite impressed with FreeBSD ("Wow, you mean it comes with a C
*and* C++ compiler FOR FREE?!?", etc.) so I might have several more
converts in a couple of weeks. :)
