short version:  trying to boot from cd, doesn't work.

long version:

I have a power mac 7500 with 604 upgrade:
0 > dev / ls 
FF828F80: /PowerPC,604@0
FF829230:   /l2-cache@0,0

I managed to boot the 1.4.2 floppy once on the machine and am now trying
to boot from a 1.5_BETA cd.  I placed 'ofwboot.xcf' and a kernel in the /
directory of the CD.  The CD does not have a HFS partition.  The CD-ROM
drive is on the external scsi bus.

Open Firmware, 1.0.5
To continue booting the MacOS type:
BYE<return>
To continue booting from the default boot device type:
BOOT<return>
 ok
0 > printenv load-base 

load-base           600000              4000 
 ok
0 > boot scsi/sd@4:0,ofwboot.xcf unrecognized Client Program formatstate
not valid
 ok
0 > boot scsi/sd@4:0,OFWBOOT.XCF unrecognized Client Program formatstate
not valid
 ok

Is 'ofwboot.xcf' working in the 1.5_BETA snapshot?

Thanks
