[SPARCbook] RedHat 6.0 boot floppies on sparcbook... can't load root disk image

[William M. Perry]

Anybody seen this one?  I cannot boot using 'boot floppy' or 'boot
/iommu/sbus/espdma/esp/fd at 5,0' - says no device found.  Booting from sd at 5,0 
works for the boot floppy, and I see:

scsi0: Sparc ESP100A-FAST
scsi : 1 host.
  Vendor: ADTX  Model: AXSITS2532U 011D Rev: K2.1
  Type: Direct-Access                   ANSI SCSI revision: 02

VFS: Insert root floppy disk to be loaded into RAM disk and press ENTER
[ --- I swap floppies and hit enter --- ]
VFS: Insert root floppy and press ENTER
[ --- I hit enter again --- ]
VFS: Cannot open root device 02:00
Kernel panic: VFS: Unable to mount root fs on 02:00
Press L1-A to return to the boot prom

Each time I hit enter there appears to be _NO_ access of the floppy drive.
Anybody been able to work around this?

All help deeply appreciated.  Am downloading the entire RH6.0 distro for
sparc right now (poor little ISDN line is smoking :)
