give an explanation of the problem I have with SRM on my LX164 machine?

Somewhat unlikely, as that's a message that one sees on any LX; it
indicates a weakness of the PYXIS core-logic chipset used there (it
also shows up on MIATAs).

I tried to disconnect SCSI controller (actually I just disconnected
scsi disk) and try to boot from ide disks.<br>
The SRM loaded without problems.<br>
Linux started to complain about dma problems and lost interrupt during
ide initialization and hang on initialization of<br>
ncr825 adapter. Could it shed some lights on why SRM could crash when
scsi disk is connected and srm is trying to reset scsi bus? Same
problem when it tries to access floppy.<br>
I am supprised how different srm and alphabios in terms of initializing
and handling of the same hardware.<br>
May be there is some undocumented command that I could use to switch
off srm turbo mode? :)<br>
<br>
Thank you,<br>
