[rescue] rescue DBlade 100 NVRAM replacement

[Mark M]

Are we talking using the wrong part number or am I missing something? I've
been using m48t59's in my 4u systems. That said, my b150 is running right
now with an unprogrammed one (dead batt) from an ultra30(RIP), it boots
solaris 10u13 fine, it just complains a little. It's OBP is the latest.

The only difference in the blade100/150 OBP that I'm aware of is the STUPID
reprogramming method, detailed here:
https://github.com/MrSparc/idprom-repair (the method works, but N.B.
there's an address difference in the 150). Generally it seems folks just
use a system without a stupid OBP to program their chips.

I'm waiting on a THIRD and 4th attempt at M48T59Y-70PC1s from china, so
far, they've all been fake and for whatever reason my 150 won't post
reliably with either piggybacked cr2032 I've built(I've done it for other
systems a bunch), but works fine with a good one from a U60. I have a
feeling this machine is going to continue to be absolutely fascinating if
incredibly slow.

Anyway, there are US domestic ebay sellers happy to rob you for a new
looking chip if that's the concern. I've had 0 luck with chinese sellers,
but I'll pass along a link if the 3rd and/or 4th attempts are good.

Good luck.
