It's still true, OBP has never had any problems related to large IDE disks 
on the mainstream Sun platforms: Ultra 5/10, Sun Blade 100 and the OS 
doesn't use OBP for disk-related activities after booting so problems found 
after booting (when using format, etc) are not due to OBP.  The 9GB and 
32GB limits were always in the OS drivers and firmware upgrades were not 
required to remove them, just OS upgrades.

Currently Solaris and OBP support IDE disks up to the 128GB (137 
"marketing" GB) limit of the ATA-5 specification.  Even if ATA-6 support is 
added to the Solaris drivers the IDE host adapters in the current machines 
do not support ATA-6 addressing.

Richard: have you run full POST while monitoring the results on the serial 
port?  Did you open the machine recently?  Usually the last thing you 
touched would be the first suspect.  Maybe you damaged the IDE ribbon cable 
while swapping disks in and out?  Maybe it's just not seated properly?  If 
you did open the machine then reseat everything: cpu module, memory, all of 
the ribbon cables.
