SUMMARY: problem booting SS10 (continued)

I got another interesting reply to my problem (see below).
Can anybody explain what this little bit of FORTH magic is doing
and verify whether it will solve my problem?

Since my previous posting, I have verified that I have a firmware
revision of 4.16 in the Maxtor 207MB drive, which is below the
required rev level.

Luckily, I have an internal drive in another SPARCstation which
I can swap with this one...
