Hi,

I proceeded with the tests you requested.

It worked. It is important to put them into /

here is my report: It was difficult to get the "first" booting, having 
no working cdrom, no floppy. I can't install from OpenBSD either I 
guess. I resorted using my resuscitated SS10 (yay! spare cable arrived 
and reused my existing HD, no wide-scsi upgrade) to install the bootblocks.

Once booting, I installed them one after the other

Here my report
File:boot.388000-2005-02-26 -> boots
File:boot.388000-2005-04-28 -> boots
File:boot.388000-2005-06-21 -> boots
File:boot.388000-2005-07-11 -> boots
File:boot.388000-2005-08-15 -> boots
File:boot.388000-2006-01-26 -> boots
File:boot.388000-2006-11-17 -> fails!

I hope this help, it took me several hours of attempts. Things are not 
as fast as it used to be on the IPC, certain things got slow (login and 
"su-" for example, as well as a certain step of the boot process itself, 
after motd).

Now the only way to get the disk booting again is to attach it to 
another system and revert the boot block to 2006-01-26 right?

If it helps fixing or you have other bootblocks to test, let me know.
