Following the cdrtools README.sunx86boot instructions (but using Solaris 8 2/02) I still have to a have a floppy to start the install process or I get the message:

Direct CDROM boot failed. Check the system BIOS to make sure that CDROM
boot is enabled then retry the boot, or reboot using the boot diskette.

In the final system there is no floppy drive so I need to remove this dependency. If the original Sun CD is used, no error and no floppy is required so this rules out BIOS setting?

I have modified the README.sunx86boot instructions because the S8 equivalent of:

star -cPM -C /vol/dev/dsk/c1t1d0/multi_icd_sol_8_202_ia/s2 .

complains that the path is not a directory, using instead:

star -cPM -C /cdrom/multi_icd_sol_8_202_ia/s2 .

and the mkisofs line uses slice 0 extracted using:

sdd if=/dev/dsk/c1t0d0s0 of=s0

because I wish to modify the content of slice 0 to edit the sysidcfg/startup files. Thus the mkisofs becomes:

mkisofs -log-file mkisofs.log.3 -G genboot \
-no-emul-boot -b .bootimage -c .catalog \
-R -o bootcd.iso -sunx86-boot ../s0 isodir

What am I missing that prevents the CD booting by itself?

TIA

From comp.unix.solaris :

"Try burning your CD not with "bootable" flag on,
but create a track image and copy your iso file in that track."

Thanks, but could you possibly expand on that?
Sorry to appear dense.

Do you mean drop the -sunx86-boot flag (which isn't mentioned in manpage, but it is used in the README). And how does one create a track image?

Below is the exact sequence I currently use:

# --- Start
dd if=/dev/dsk/c1t0d0s0 of=s0
mkdir s0_mnt
lofiadm -a `pwd`/s0 /dev/lofi/1
mount /dev/lofi/1 `pwd`/s0_mnt
rm s0_mnt/etc/sysidcfg
vi s0_mnt/etc/sysidcfg
vi s0_mnt/sbin/startup
umount /`pwd`/s0_mnt
lofiadm -d /dev/lofi/1

readcd dev=1,0,0 f=CD.out sectors=0-32
sdd if=CD.out bs=446 count=1 of=mboot
sdd if=CD.out count=1 of=pboot
sdd if=CD.out count=31 iseek=2048 of=bootblk

sdd if=mboot -fill of=eltoritoboot
cat pboot >> eltoritoboot

cp eltoritoboot genboot
cat bootblk >> genboot

mkdir isodir
star -cPM -C /cdrom/multi_icd_sol_8_202_ia/s2 . | \
star -xp -xdot -C isodir

cp eltoritoboot isodir/.bootimage

mkisofs -log-file mkisofs.log.3 -G genboot \
-no-emul-boot -b .bootimage -c .catalog \
-R -o bootcd.iso -sunx86-boot ../s0 isodir

cdrw -C -i bootcd.iso
# -- End

Ta, Bob.
