Burned S9 1of2 sparc iso image on s8_x86 HP scsi cdrw and alternatively with
Nero under w2k on ATA-CDRW (Both CDs were equivalent in all tests).

The same CDRW on the same system could mount and read (with and w/o vold)
the first (hsfs, cXtXd0s0) partition. It couldn't see the other (ufs)
partitions (I/O error) - blocksize on CDrom?

Tried to mount the partitions with a Teac CD-523S on SparcClassic (S2.5.1):

hsfs-Partition could be mounted w/o vold - the directories were seen, but
files were not readable.

ufs-Partition (cXtXd0s1) could be mounted and copied. Booting from CD was
not possible - blocksize?

Putting together s0 from the intel machine and s1 from the sparc I could
setup an install server on the intel S8 machine and install S9 on the
Classic (128 MB RAM). Worked much more effektive than S2.5.1.

Then I changed the CDrom on the Classic, it was now a Toshiba XM-3701TA (no
blocksize 512/2048 Jumper).

This CDrom could mount (vold) and read any ,normal' CD - but not the S9
1of2 - neither s0 nor s1, neither with nor w/o vold. Booting from CD was
impossible.

Best result: a further CDrom (Plextor PX-32TS) on the SparcClassic. Here a
blocksize jumper was present and set for 512. The machine could boot
(bootpath cdrom1:d) and install from cdrom. Without volume management it
could mount each of the partitions (hsfs and ufs). Remaining drawback: with
vold only ,normal' CDs were readable, but none of the S9 1of2 partitions,
nor 2of2.

Hope it provides some hints for others.
