What drive did you end up using (it's not said in the post), if it's a Zulu then what's it currently configured as?  From memory you need 3GB or more if you're taking a default Irix 6.5 full user install with desktop utilities.

Generally I don't use FX for any customization because the SGI disk label, partition table in other parlance, has some strict requirements and requires several partitions just to operate. It naturally tries to make the root file system volume (/) the largest as it can if you just default everything pretty much like Windows GPT EFI does if you just say "create".  FX works in block sizes which is going to be mentally odd.

The defaults have always been sensible. If you add additional drives you can mount them anywhere you want in the file system but I normally just take the default layout given to me as there's no reason to add additional partitions and it already give you the largest file system your root drive device can support.

All I normally do is simply say "create new label" as "root drive", "write label", "exit".  Nothing else... The install process automatically formats the swap base and the main route file system for you. FX does no formatting whatsoever similar to the old DOS/Win FDISK does not formatting.

If you're getting incredibly small values for your volume then your Zulu is not configured correctly.
