Hi Jonatan
I have recently bought a TS-7500 without TS-752 and without the SD card. So, I
did this:
-To connect I used telnet, because I have no SSH till I put my root pass
inside, the full debian distro. Inside the 7500 I found TSLINUX so, I made the
changes you said:
1. rm linuxrc; ln -sf /linuxrc-sdroot /linuxrc; save
2. vi linuxrc-sdroot
#if [ "$bootdev" == "0x1" ]; then
mount -oro /dev/nbd9 /mnt/root
#fi
(because you said, comment the condition, so I only comment it, right?)
3. I took a microSD, formatted in ext3, and:
dd if=/dev/mySD of=images.dd
I tried with these to images:
2gbsd-2.6.36-nov122010.dd.bz2
2gbsd-eclipse-latest.dd.bz2
4. Once I have placed the SD and changed what you said I type
reboot inside TSLINUX, but, nothing happens, the changes Ive made turn back,
and I cant load Debian from SD.
I think that could be a wrong image, or, wrong command from TSlinux but,
Please, If there's something missing, or some other steps you know that I'm
missing, let me know. Which image did you use to get it working, I'm freeze in
this point, so I cant start with my TS, help will be very important
