.ISO help - karynroberts - 11-22-2021
I recently downloaded Silicon Graphics General and Platform Demos 6.5.12 1 and 2 of 2 .iso - anything special getting them read or mounted under IRIX? Thanks.

IRIX doesn't have loopback mounts (the ability to mount a file as a disk image), so you would need to burn them to CD-R. Nostalgic, I know.
Any CD burning program should be capable of that; my own favorites are Toast (mac) and cdrecord (avail for OSX, Irix, Linux, BSD, etc)
Once the CD-R has been burned, you can either have it mount automatically using the mediad(1) service, if it is enabled; or manually, by typing
Code:
# mkdir /CDROM
# mount -t efs -r /dev/rdsk/dks0d4s7 /CDROMRE: .ISO help - karynroberts - 11-23-2021

Well shoot - I'll burn under Arch Linux then - and yep, I do have an external CDROM. Thanks for the reply!

Make sure you burn using DAO mode. As I've discussed at length, any CD issued by SGI is not an ISO-9660/RockRidge/UDF/Joliet type -- it's an SGI EFS image.

To get gapless audio tracks you do need to use disk-at-once mode, but it makes no difference for plain data CD-ROMs.

The reason I stated this is because the two most popular OSes, macOS and Windows, particularly care about file extensions as does most GNU/Linux DEs. If you try to burn an EFS image with the built in (since 7) ISO burner, it will make a coaster. Have fun with that. Same with the diskutil for macOS, which may or may not in the 10 years since I was a macOS user regularly have removed that functionality, because Apple gonna innovate.
I don't wanna be a skipping CD here. Just, the ISO extension standard refers to the ISO-9660 and related CDFS types, and the proliferation of it as a generic term is a confusing thing, but something humans are prone to do. In this part of the world, "Kleenex", not tissue, is the common term for what you use when you have a sniffle. Same with "Frisbee", it's a trademark. We genericize terms, and it's not necessarily a good thing.

EFS images with the .iso extension actually burn with no drama at all on current macOS - I've done it many times. Just right click on the file and select 'Burn to disc'. Easy.
