Thanks to ranman I'm hacking away on my IA-1.
I found that I could make changes (like resetting the root password and editing config files) by simply remounting / rw.
mount / -o remount,rw
mount / -o remount,ro
HOWEVER - this doesnt work of /var changes (var is recreated from a gzip file in /etc) and for /dev entries.
I added pegasus to the /etc/module file and now I can network the IA-1 with a D-Link DSB-650TX. I have a Linksys USB-100TX but it just doesnt want to work.
By adding usb-storage, scsi_mod and ide-scsi to modules the IA-1 can now recognize my
USB ZIP 100 drive and Iomega USB CDROM.
But although it recognizes them I can seem to access them. I created the SCSI /dev entries but they are dead (and /dev entres diappear on reboot).
Has anyone successfully used USB storage devices on IA-1/Jailbait6?
