Hi,
the T5240 has no onboard video. It is controlled via a serial port (that is
where you get OBP and the OS console). I tried booting HelenOS on a
(physical) T5240 a few years back. I might not remember correctly, but I
think it did something, but did not fully boot up (or even fully initialize
the kernel). T1000/T2000 should mostly work, T4+ doesn't do anything at all.
I have access to a T5240 so I could try it again if there was interest.
So you have access to a physical machine? I was not aware that Qemu could
emulate a T5240.
Cheers,
Jiri

not on sun4v. In fact, I am not aware that these machines had video. I
assume you would like to attach a keyboard over USB. But then, how would
you use it without video? There is probably some non-trivial amount of
debugging and tweaking of our USB stack to run on these systems.
On sun4u there is a dormant and old (i.e. not supporting our device
driver framework) support for some Ultra 5 and Ultra 60 video and
keyboards, but since we are using it with the QEMU sun4u machine, we
switched that to the serial console and made it work with the DDF.
Cheers,
Jakub
