The arcboot.ip32 is for SGI O2, the arcboot.ip22 for SGI Indy.
The arcboot.ip32 at least executes fine on my SGI O2. (it is MIPS32
binary)
I need to check if ARCS can execute arcboot compiled to ELF64
binary.

best regards

Grub is cross-compiled for platform arc.
Isn't arc the right choice? I thought ARC/ARCS is the prom 
inside the SGI machine.

sgi O2 supported?

2017-01-07 Thread Waldemar Brodkorb
Hi,

can I use grub to bootup Linux/mips64 from SCSI disk on a
SGI O2 machine?

I cross-compiled grub (git hash
07662af7aed55bcec448bc2a6610de1f0cb62100). 
The toolchain is fine, I can bootup a Linux system via TFTP.

I create a grub.img with following modules included:
boot linux ext2 part_dvh normal

I copy grub.img with dvhtool to the volume header and
try to bootup:

> setenv OSLoader grub
> boot
341112
Cannot load scsi(0)disk(1)rdisk(0)partition(8)/grub.
Range check failure: text start 0x881ffde0, size 0x53478.
Text section would overwrite an already loaded program.Unable to
execute scsi(0)disk(1)rdisk(0)partition(8)/grub:  not enough space
Unable to load scsi(0)disk(1)rdisk(0)partition(8)/grub: not enough
space

Seems like the load address is bad?

Is it possible to use grub for this task?

best regards
 Waldemar
