If you have a Solaris 8 4/01 or newer, and you want to install
the Solaris 8 via the network is recommendable to use jumpstart:

An undocumented tip is to add in the /etc/system the
following two lines:
set rlim_fd_max=8096
set hsfs:nhsnode=8096
and then reboot.

a- Create a big Filesystem /jumpstart (2Gb or more)

b- Insert the Solaris 8 CD 1
cd /cdrom/sol_8_401_sparc/s0/Solaris_8/Tools
./setup_install_server /jumpstart/OS/Solaris_8_2001-04

c- when you was received the message "Install Server setup complete"
eject cdrom

d- Insert The Solaris 8 Cd 2
cd /cdrom/sol_8_401_sparc_2/Solaris_8/Tools
./add_to_install_server /jumpstart/OS/Solaris_8_2001-04

e- when you was received the message "Processing completed successfully"
eject cdrom

f- share -F nfs -o ro,anon=0 -d "Jumpstart" /jumpstart
(remember /etc/init.d/nfs.server start if not yet started)

g- shareall

h- Make the entry of the client in the /etc/hosts

i- make the entry of the client in the /etc/ethers

j- create a /jumpstart/sysidcfg file
system_locale=en_US.ISO8859-1
TIMEZONE=GMT-3
network_interface=hme0 {netmask=255.255.255.0
protocol_ipv6=no}
terminal=vt100
security_policy=NONE
root_password=<your_/etc/shadow_passwd>
name_service=NONE
timeserver=localhost
keyboard=NONE
monitor=NONE
pointer=NONE
(you need to replace with the apropiate values see: man
sysidcfg)

k- create a generic rule file
any - - generic_profile -

k.1 or create a specific rule (you need to create the apropiate
subdirectories/files)
model SUNW,UltraSPARC-IIi && memsize 256-512 && disksize c0t0d0 8192-194560 - Profiles/FE/normal_FE.profile Finish/install_recommended_patches.sh

model SUNW,UltraSPARC-IIi-cEngine && memsize 256-512 && disksize c0t0d0 8192-194
560 - Profiles/FE/normal_FE.profile Finish/install_recommended_patches.sh

model SUNW,UltraSPARC-IIi-cEngine && memsize 1024 && disksize c0t0d0 8192-194560
- Profiles/FE/robust_FE.profile Finish/install_recommended_patches.sh

model SUNW,Ultra-80 && memsize 2048-6144 && disksize c0t0d0 8192-194560 - Profil
es/BE/robust_BE.profile Finish/install_recommended_patches.sh

model SUNW,Ultra-80 && memsize 512-1024 && disksize c0t0d0 8192-194560 - Profile
s/BE/normal_BE.profile Finish/install_recommended_patches.sh
# any - - Profiles/basic.profile -



l- create the generic_profile file
install_type initial_install
system_type server
root_device c0t0d0s0
partitioning explicit
filesys rootdisk.s0 3072 /
filesys rootdisk.s1 1024 swap
filesys rootdisk.s3 9216 /opt
filesys rootdisk.s5 3072 /var
filesys rootdisk.s6 720 /var/spool
filesys rootdisk.s7 128 /export/home
geo N_America
geo S_America
locale en_US
cluster SUNWCall
package SUNWpmux delete
package SUNWpmu delete
package SUNWpmr delete
package SUNWpmowr delete
package SUNWpmowu delete
package SUNWpmowm delete
(customize with your preferences)

m- Check your rules file
cd /jumpstart
cp /jumpstart/OS/Solaris_8_2001-04/Solaris_8/Misc/jumpstart_sample/check .
./check
(this step create a rules.ok file needed for the installation)

n- run the add_install_client
cd /jumpstart/OS/Solaris_8_2001-04/Solaris/Tools
./add_install_client -e <MAC_client> -i <IP_client> -c <your_ip_jumpstart_server>:/jumpstart <client_machine_name> <platform>


o- if the jumpstart configuration is ok
in the client side at the boot prompt
ok> boot net - install

See the apropiates man pages and good luck, and excuse my poor english (I speek spanish)
