Hello hobbists and pros!
I'm having a really hard time into installing Gentoo on Silicon Graphics hardware!

I'm the proud owner of an Octane2 ("IP30") with:

- 512 megs RAM
- R12000 single CPU
- V6 graphics (aka Odissey)

I've got no cdrom reader! I've tried really hard to adapt the 2006 SGI LiveCD from here:
http://ba.mirror.garr.it/mirrors/gentoo/experimental/mips/livecd/x-rc6/
to be "burnt" and booted from an hard drive with no success.

Then I built from scratch a Gentoo installation on a virtual machine on my modern pc.
From there, I'm literally STRUGGLING to compile a MODERN kernel for the Octane to boot from and to proceed with a current stage3 install.

The older - prebuilt - kernels that can be found online don't allow to use newer stage3! You can find the
kernels here:
https://dev.gentoo.org/~kumba/mips/old-netboot/testing/
Did support stopped in 2006?

On the virtual machine I've managed to install the "mips64-unknown-linux-gnu-8.2.0" crosscompiler using crossdev:
Code:
crossdev -s1 --target mips64-unknown-linux-gnu
gcc-config  mips64-unknown-linux-gnu-8.2.0


I've installed mips-sources tailored for my system with
Code:
USE="ip30" emerge --ask sys-kernel/mips-sources


I've customized .config following various tutorials... finger crossed... but no avail:
Code:
make vmlinux modules CROSS_COMPILE=mips64-unknown-linux-gnu-

...fails with a generic error!I can provide more details if requested!
Hope I sort out this mess!!!
Thanks to anyone willing to help!
Cheers,
qzu

Sorry Xavier for the inconvenience.
Did anyone ever used those patches?

https://dev.gentoo.org/~kumba/mips/patches/

Does the mips-sources version and patch version shall be identical?
What are the steps to accomplish that?
Thank you very much!

As per subject...
What would be the "scientific" way to netboot via TFTP and to chroot into the LiveCD:

http://gentoo.mirrors.tds.net/pub/gentoo/experimental/mips/livecd/x-rc6/livecd-mips3-gcc4-X-RC6.img

I've managed to dump the .img with "dd" on a disk, netboot and "uncleanly" chroot... e.g. "startx" will fail!
Hints anyone?
Thanks,
qzu

PostPosted: Sat Feb 16, 2019 6:21 pm    Post subject: CDRECORD arguments Reply with quote

Hello everyone!

Finally found an external scsi cdrom drive... Tested and working under IRIX: copied huge files from a cd and tested with "diff".
I'm trying to burn the LiveCD img file.

This:
Code:
cdrecord -vv -pad dev=6,2,0 -tao livecd.img

Doesn't work! Can't even load Sash because of a "seek" unrecoverable error... I may take a screenshot tomorrow.

Anyone can help with the correct tweaks with cdrecord arguments to burn this strange, hybrid "beast" of a CD image?

Thank you very much,
Francesco
