Here's my silo.conf:

# Example of how can be silo.conf set up
partition = 1
root = /dev/sda1
timeout = 300

default = Linux

image = /boot/kernel-genkernel-sparc64-2.6.24-gentoo-r3
        initrd = /boot/initramfs-genkernel-sparc64-2.6.24-gentoo-r3.bmeyer
        label = Linux2624gr3
        alias = Linux
        append = "video=atyfb:off real_root=/dev/sda1"


The 'initrd' image is one I modified. The original genkernel generated image is /boot/initramfs-genkernel-sparc64-2.6.24-gentoo-r3 and did not seem to have a /lib/firmware directory, nor did it seem to have any modules, such as the one I very much need - qla2xxx. I generated the new one via the following method:

zcat -d ../initramfs-genkernel-sparc64-2.6.24-gentoo-r3 > initramfs-genkernel-sparc64-2.6.24-gentoo-r3.file
cpio -i -d -H newc --no-absolute-filenames < ./initramfs-genkernel-sparc64-2.6.24-gentoo-r3.file

I then added the following directories:
/lib/firmware
/lib/modules/2.6.24-gentoo-r3/kernel/drivers/base
/lib/modules/2.6.24-gentoo-r3/kernel/drivers/scsi
/lib/modules/2.6.24-gentoo-r3/kernel/drivers/sbus

I also did a 'touch' of all the module names in /etc/modules to try to add them. But I don't see them getting loaded right.

And created a new initrd via:

find ./ | cpio -Hnewc -o > /boot/initramfs-genkernel-sparc64-2.6.24-gentoo-r3.bmeyer.cpio
gzip initramfs-genkernel-sparc64-2.6.24-gentoo-r3.bmeyer.cpio
mv initramfs-genkernel-sparc64-2.6.24-gentoo-r3.bmeyer.cpio.gz initramfs-genkernel-sparc64-2.6.24-gentoo-r3.bmeyer

The system boots, and I think it now finds the initrd image - my first error was I had 'initrd' instead of 'initramfs' in silo.conf; however, it is still not working.
It theoretically loads the modules (though I see no evidence of the qla2xxx controller being found), starts mdev, and tries to mount /dev/sda1 - at which point it can't find /dev/sda1 since the qla2xxx controller has not yet been found and initialized, and crashes. Despite the message about starting a shell, pressing 'q' or anything else - I can't use STOP+A to get back to the PROM, nor can I use CTRL+ALT+DEL to restart the system. I have to power-cycle to reboot.

Per #3 - I do seem to have CONFIG_PROM_CONSOLE enabled. I will try that the next time I build the kernel. Thanks for the tip. Right now I just need to get the system fully booting. (Then I can rebuild the kernel appropriately.)

Thanks!

Ben

Hi Ben,

Good about #1.  There's actually a lot of good information on the www 
about OpenBoot.

As for #2, what does your silo.conf look like?  In my experience <which 
doesn't involve genkernel>, an initrd isn't required.  Can you boot the 
box from the install disc and check out the current kernel config?  I'd 
say disable initrd and any references to it (and make sure that you're not 
loading disk controllers as modules), and then make sure silo.conf isn't 
trying to boot from one.

For #3, are you using the PROM framebuffer as well as the ATI (aty) one? 
Maybe toggling the PROM framebuffer console is the solution...

Here's the relevant snippet from my Ultra 10's kernel config; hope that 
helps a little:

#
# Console display driver support
#
# CONFIG_PROM_CONSOLE is not set
CONFIG_DUMMY_CONSOLE=y
CONFIG_FRAMEBUFFER_CONSOLE=y
# CONFIG_FRAMEBUFFER_CONSOLE_ROTATION is not set
CONFIG_FONTS=y
# CONFIG_FONT_8x8 is not set
# CONFIG_FONT_8x16 is not set
# CONFIG_FONT_6x11 is not set
# CONFIG_FONT_7x14 is not set
# CONFIG_FONT_PEARL_8x8 is not set
# CONFIG_FONT_ACORN_8x8 is not set
CONFIG_FONT_SUN8x16=y
# CONFIG_FONT_SUN12x22 is not set
# CONFIG_FONT_10x18 is not set
CONFIG_LOGO=y
# CONFIG_LOGO_LINUX_MONO is not set
# CONFIG_LOGO_LINUX_VGA16 is not set
# CONFIG_LOGO_LINUX_CLUT224 is not set
CONFIG_LOGO_SUN_CLUT224=y
# CONFIG_FB_SPLASH is not set
