I recently upgraded from a 486-33 to a Cx5x86-120. The only problem I had was my 486-33 kernel didn't find my modem ``at isa? port "IO_COM1" tty irq 4 vector siointr''. To resolve this problem, all I did was rebuild the kernal after rearranging the order of sio devices in my kernel config file so the modem was no longer the first sio device. Except for this minor problem, everything seems to work just fine with the Cx5x86. As for the performance improvement, I have two real-life measurements: First, I have a rather large library that took 15 minutes 40.20 seconds to make on the 486-33 and only takes 6 minutes 59.99 seconds on the Cx5x86-120. Making the library of course does a lot of disk IO and also a lot of writes to the xterm. And second, I have a simulation that took 1:51:24.82 on the 486-33 and only 38:54.05 on the Cx5x86-120. The simulation does a lot of writes to the xterm but no disk IO and no floating point; it is mostly tight loops that probably fit in cache. These numbers are in line with my expectations; I'm quite happy with the Cx5x86! tim -- Tim Singletary, August Automation Inc., (301) 286-8606
