I have a PC164SX and I'm using SRM and aboot. Do you find that it randomly wont reboot sometimes? I cannot off hand remember the error message but it says to press some key (like reset, but not the reset key) and only a power cycle fixes it. I've never been able to reliably reboot the alpha, leaving aside kernel not working type problems.
Yep, same here with SRM, which is why I went back to MILO. See my posts over the past couple of weeks to the list for details.
