[9fans] Booting plan9 from an iSCSI disk

[9fans] Booting plan9 from an iSCSI disk

[gdiaz]

Hola,

Has anyone done this?

I have access to a cheap hardware which could be a nice plan9 cpu server, the only thing does not work
is the iSCSI disk (or i think so, look at the lspci below)

I suppose the bios of the machine supports booting from iSCSI, so i think i could put a 9load or
9pxeload there,  but 9load is not able to load a kernel from iSCSI and i suppose i can't instruct 9pxeload
to boot from specific server without using bootp/dhcp to boot, right?

any tips on how to make this little thing work? (besides writing iSCSI support for 9load)

here is he lspci output (it is a dualcore atom 1.6ghz intel board, 1gb of ram):

Hi !

Use 9P instead of iSCSI. In My setup, I use small IDE Flash drives (128Mb)
They works just fine ! :)

Hello

I just need to boot the kenel, this machine is rented, i can't change  
any hardware configuration, i can just try to get plan9 running there  
with the help of qemu. . .

I installed  a fossil terminal, now i need to instruct 9load to read  
the kernel from /dev/sdB0, and if the kernel loads, i need to instruct  
it to use 9grid.es as the fs and auth.

I will post the results of these tests if they are possitive.

thanks!
