Problem in booting x86 Solaris 10 into 32-bit Mode

Thanks for the quick post to this matter. I've had a check on the system, specifically in /kernel/drv and I've found the 32-bit nvidia and 64-bit drivers:-

bash-3.00# cd /kernel/drv
bash-3.00# ls -lrt nvidia
-rw-r--r-x   1 root     sys      8643504 Dec 12  2007 nvidia
bash-3.00# file nvidia
nvidia:         ELF 32-bit LSB relocatable 80386 Version 1

bash-3.00# cd /kernel/drv/amd64
bash-3.00# ls -lrt nvidia
-rw-r--r--   1 root     sys      11220560 Dec 12  2007 nvidia
bash-3.00# file nvidia
nvidia:         ELF 64-bit LSB relocatable AMD64 Version 1

Do the drivers appear to be in the correct place? Besides a re-install of the driver - is there some way to temporarily disable the attempted load up of the nvidia driver at bootup? for this intial phase, I'm not too concerned if it doesn't boot up into the Solaris Java Desktop interface as we'll be remotely accessing the system via telnet for most of the time.

Thanks

You could try booting into the failsafe mode, and then run kdmconfig. If you configure to use Xsun instead of Xorg, you should be able to choose the VGA driver and complete the normal boot up.

Not to sidestep the question, but you do not need to boot in 32-bit mode to run 32-bit programs. When in 64-bit mode, you can run both 32-bit and 64-bit programs.

I believe you can completely disable the graphical mode login and fall back to the text console by running this commands as root:

svcadm disable cde-login:default

Hope this helps,

Hi,

I've booted  into failsafe mode (via GRUB) andit asks if I want to mount solaris 10 8/07 s10x_u4wos_12b X86 (/dev/dsk/c1d0s0) - "y" was selected and this is mounted to /a.

I've not used kdmconfig before - but I've found that it's in /usr/sbin - I've tried to run it from this directory but I think it's just a symbolic link to the /openwin/bin/kdmconfig and as such comes up with "not Afound". Sorry for the newbie question but how would I initiate kdmconfig

Thanks

Michael

Thanks for the input Christophe,
I was under the impression that you could run both 32-bit and 64-bit apps in 64-bit mode but came across some issues when attempting to install some 3rd party software which claims is only supported on x86 32-bit solaris. It was suggested that we boot into 32-bit mode to see if this makes a difference.

I've used svcadm to disable cde-login but when I reboot (into 32-bit mode) I still get that same problem with the nvidia and it then reboot itself. I just typed in the scvcadm command - do i need to somehow save it befoer I reboot in solaris 10?

Thanks

Hi,

We've managed to disablethe CDE so that now when we boot up (in 64-bit mode), we just get the command prompt. Whilst in 64-bit mode, I ran kdmconfig and specified that XSun should be used,we then changed the video device to use "XF86-VGA VGA-Compatible video cards". This was then tested (in KDMConfig and the driver seemed to be ok). I then ran eeprom boot-file=kernel/unix to set 32-bit mode and then resrarted the system.

when the system came back up again, it still reported the same issue with the nvidia driver and then rebooted itself. I was just wondering if I need to take any other steps after making the changes in kdmconfig or should I have selectd a different VGA driver? Alternatively, are there any files tat I can edit to explicitly disbale the loading o the nvida driver?

Thanks

Michael
