I just bought
a new CD-RW drive -- a Sony CRX145s -- and am curious
about whether it may read the 512-byte blocks necessary for using it
as a backup boot device on my VAXen, Sparc, SGI, etc.
Does anyone know whether this, or just for information, some other
CD-RW unit, will do such a thing?
Haven't tried my CD-RW on a non-Intel box as boot device, but I know
that the 512-byte boot block is not the only issue. For instance, I
have a Sony 8x reader with an IBM "microcode upgrade" that will boot my
SparcStation, every RS6k I own, and my Alphas, ***unless*** it's a
VMS/OpenVMS CD. The BabyVAXen also won't boot off it. The Indy won't.
OTOH, My Plextor 32x, May It Rest In Peace (I dropped it!), would boot
all the above except VMS CDs.
I know that early RS/6000s did some sense checking that narrowed the
field considerably. I _guess_ that VMS does the same. About the rest,
I'm clueless.
I don't need to boot off it, but I would like to use my Yamaha CRW2200S
16-10-40X CD-R/W in my RS/6000 397, but I can't get the SCSI to recognize
the drive. I have no idea why. The drive is at ID5. The main CD-ROM in
the machine is at ID6 and is a 20X Wide Plextor, which works just fine. I
have termination disabled on all devices, and I have a wide terminator on
the end of the cable.
Peace... Sridhar
