I've updated and put cobalt restorecd images for NetBSD/cobalt 9.2:
https://cdn.NetBSD.org/pub/NetBSD/arch/cobalt/restore-cd/9.2/
- restorecd-9.2-20210807.iso.gz is a gzipped RestoreCD ISO9660 image.
- restoreusb-9.2-20210807.img.gz is a gzipped RestoreUSB image
for >=800MiB USB memory sticks on USB bootable PCs.
No functional changes RestoreCD/USB except minor fixes:
https://github.com/tsutsui/netbsd-cobalt-restorecd
and briefly tested on Qube 2:

Have fun,
