Как записать установочные образы IRIX

Что-то про такой формат даже гугл сходу молчит...

Как решение можно

well, this post somehow links to my problem with installing the V6....
i have 6.5.15 bootable....i installed them at first....then went to 6.5.25....all this with ESI.
now want to put the V6, but for many problems cant get it used when the machine boots IRIX ( the image blocks forever, you know....)
so want to make 6.5.25 bootable, let me tell you what i did...

1- put all files into directories, so they look like this:
Code:
45320   ./cd1/dist/miniroot
411972  ./cd1/dist
8640    ./cd1/stand
420620  ./cd1
65008   ./cd2/dist/unbundled
364948  ./cd2/dist
364964  ./cd2
404960  ./cd3/dist
404968  ./cd3


2- i ran this....and now got sash* and mr
Code:
mkboottape -f sa -x

but dont know how to Install sash* and mr in the volume header /dev/rdsk/dks0d2vh , in fact it seems /dev/rdsk is a link to /hw/rdisk an there, is dks0d2vh, but still dont know how to install sash* and mr there.

3- dont know from where to get fx.* and ide.* so grabbed them from the 6.5.15 cds...
is this okay? or should i obtain them in a different way?

4-patched mkefs, and looked inside it, seemed the patch worked...
then when i ran
Code:
mkefs -v -l -f /cd1 -o /to_burn/cd1

it stalls with messages like:
Code:
Inst> /usr/tmp/target.2759/usr/stand/ide - No such file or directory
ide.IP28 failed.
ERROR: Nothing selected for installation.

i guess this does something to do with not installing sash* and mr into the volume header....

will appreciate any help, since sgiaddict seems to be down now...
greetings from the south
