New builds are announced on the devel mailing list.
XO-1.75 and XO-1.5
To install from Open Firmware on an unlocked XO-1.5 or XO-1.75, download a .zd file to a USB drive. Choose the correct one: there are several. Files which end in .zd2 are for 2GB media and .zd4 is for 4GB media.
Insert the USB drive into the XO-1.5, get to the Ok prompt and type:
fs-update u:\osXX.zdN
Where osXX.zdN is the file you downloaded, for example os22.zd4.
XO-1
To install from Open Firmware on an unlocked XO-1, download the .onu and .uim files to a USB drive.
Insert the USB drive into the XO-1, get to the Ok prompt and type:
update-nand u:\osXX.onu
where osXX.onu is the .onu file you downloaded, for example os22.onu.
(Watch out, there's a trap. Never use copy-nand for this file format. copy-nand was for previous releases with .img and .crc files, but we no longer use it for .onu and .uim files. copy-nand might seem to finish okay, but your XO-1 won't start. If that happens, do it again using update-nand as above.)
