This machine is in my business room, and I cannot touch it until next monday.
So I cannot report the info of seE0part of this machine now. However, I'll retry what happened here. 1) replaced only /sys/src/boot/pc/sdiahci.c from the format CDROM to your 9atom CDROM. 2) It booted nicely, meaning no long wait to detect and fail CDROM 3) system came up safely, and I can do anything, but only no /dev/sdE0/other directory. 4) Then, I dispatched the disk/prep command interacyively. 5) Yes, it reports the right partition table including 'other' 6) then, I wrote the table to the disk. 7) exit disk/prep 8) Now, I see /dev/sdE0/other directory. 9) therefore, ofcourse, I can mount that partion safely. 10) however, after end the session, and rebooted the system again, then, /dev/sdE0/other disappeared again. This the precise story I experienced. Kenji PS. I can see the list only after next Monday night.
