I have an intermittent problem where ncr53c875 will loop trying to
reload the script while detecting ID 2, Micropolis 3243NT. Happens on
2.0.34 and 2.1.106, both SMP, no overclocking. Is this hardware or
software? You don't have to tell me that the 3243 is a pile of crud,
this is the third replacement.
