Hi Marc,
Finally I managed to reach my old flat where I keep my old XT. I did
modifications to ELKS as in the attachment and booted it from floppy
(still don't know how to boot it over XT-IDE from HD image! I managed to
buy, just for ELKS experiments, 32MB CF card in 2018 from some on-line
store in Japan! dd to /dev/sdb1 doesn't seem to copy bootstrap code to
the boot sector, dd directly to /dev/sdb creates whole of a mess in place
of partition table, and it still doesn't boot).
As I booted newly built ELKS, this time there was no interrupt acquisition
error, frankly no errors at all, brief message that ne2k driver was
initialized properly.
I tried to ping it by mac address (found some macping script on
stackoverflow: https://stackoverflow.com/a/43478858) unfortunately, no
reply (alhough the diodes on the RJ-45 socket were blinking during that).
It would be easier to have IP address set, but I couldn't find anything
like that in menuconfig. I guess more progress will be possible when I get
there next time.
Thanks,
Paul
