AFAIK the on-board SCSI controller is a FAS366 which is supported by
esp(4). Fibrechannel SBus-based controllers _might_ be supported by

That would be great. With the switch to uart(4) as the default console
in GENERIC there currently is no console support for these machines.
Marcel probably will commit a hack to puc(4) soon to make the Z8530 on
the FireHose bus work. Ideally fhc(4) should be fixed so this hack
isn't required but so far I didn't manage to get access to an E[3-5]000
series machines to test the required changes. Could you please let me
know when you got access to that E3500?

AFAIK the SBus QFE cards only have a single interrupt for all four
HMEs and the FreeBSD hme(4) doesn't take this into account.
