I have installed Solaris 8 on P3, now I am trying to install on P4 with same cd(s).
When I boot system, its checks my devices (no conflict), then ask for target to boot, I choose CD then it reboots. It wont give me option to make partion nor it install.
Can any one help me out ????

There must be something wrong with the CD, or ur hdd, becos am sure its not able to copy from the CD to ur hdd, thats why its crying so much

hi

There is a problem installing solaris 8 on p4 intel platform. There are 2 ways to surrund this. The first is to use a patch describe below, and second to use a procedure also describe below. I have use the second option and it works.
I quote from an answer I saw in the internet as well that say:

Because someone added code for the P4 ~ 1 1/2 years ago and didn't
(couldn't :-) test it?

Michael Riley suggested to completely disable the buggy setup_mca
routine, by patching a 'return' instruction as the first
instruction of 'setup_mca' subroutine:

So, try to boot from the "Software 1 of 2" CDROM; at the following
prompt ... :

____________________________________________________________________

>>
Boot path: /pci@0,0/pci-ide@4,1/ide@0/sd@1,0:a
Boot args: kernel/unix

Select the type of installation you want to perform:

1 Solaris Interactive
2 Custom JumpStart

Enter the number of your choice followed by the key.

If you enter anything else, or if you wait for 30 seconds,
an interactive installation will be started.

Select type of installation:
____________________________________________________________________

... type ( is the "Return" key):

b kadb -d

The screen should no look something like this:

Select type of installation: b kadb -d
kadb: kernel/unix
Size: 239225 + 21460 + 78200 Bytes
/platform/i86pc/kernel/unix loaded - 0x8b000 bytes used
stopped at _start: jmp .+0x63 [__start]
kadb[0]:

Now try the following patch:

setup_mca?w c3
:c

Does that work for booting into the installation solaris OS from the
cdrom and install the system?

If it works, you have to repeat the same kadb patch for booting
solaris from the hard disc drive (HDD). The initial prompt looks
a bit different, but the kadb patch should work exactly the same:

____________________________________________________________________
>>
Boot path: /pci@0,0/pci-ide@4,1/ide@0/cmdk@0,0:a
Boot args: -v

Type b [file-name] [boot-flags] to boot with options
or i to enter boot interpreter
or to boot with defaults

>>

Select (b)oot or (i)nterpreter:
____________________________________________________________________

Once the system is running, the following command should make
the patch permanent:

echo 'setup_mca?w c3'|adb -w /platform/i86pc/kernel/unix

I hope I was useful and it will help you
bye

Sha, I was able to install my solaris, but I am confused with the later part. I still can't get the patch to stay permanently. As a result I have to issue the "k badb - d" command every time my pc boots up. Am i missing something here? please respond. Do i have to hard code it inside a file or what.
Thanks
