&boot-installer-intro-net.xml; &boot-installer-intro-cd.xml; &boot-installer-intro-firmware.xml; There are three ways how to put the installer firmware into flash: Go to the administration section and choose the menu item Upgrade. You can then browse your disk for the installer image you have previously downloaded. Then press the Start Upgrade button, confirm, wait for a few minutes and confirm again. The system will then boot straight into the installer. You can use upslug2 from any Linux or Unix machine to upgrade the machine via the network. This software is packaged for &debian;. First, you have to put your NSLU2 in upgrade mode: Disconnect any disks and/or devices from the USB ports. Power off the NSLU2 Press and hold the reset button (accessible through the small hole on the back just above the power input). Press and release the power button to power on the NSLU2. Wait for 10 seconds watching the ready/status LED. After 10 seconds it will change from amber to red. Immediately release the reset button. The NSLU2 ready/status LED will flash alternately red/green (there is a 1 second delay before the first green). The NSLU2 is now in upgrade mode. See the NSLU2-Linux pages if you have problems with this. Once your NSLU2 is in upgrade mode, you can flash the new image: sudo upslug2 -i di-nslu2.bin Note that the tool also shows the MAC address of your NSLU2, which may come in handy to configure your DHCP server. After the whole image has been written and verified, the system will automatically reboot. Make sure you connect your USB disk again now, otherwise the installer won't be able to find it. There is a tool for Windows to upgrade the firmware via the network. Due to limitations in the SS4000-E firmware, it unfortunately is not possible to boot the installer without the use of a serial port at this time. To boot the installer, you will need a serial nullmodem cable; a computer with a serial port A USB serial converter will also work. ; and a ribbon cable with a male DB9 connector at one end, and a 10-pin .1" IDC header at the other This cable is often found in older desktop machines with builtin 9-pin serial ports. . To boot the SS4000-E, use your serial nullmodem cable and the ribbon cable to connect to the serial port of the SS4000-E, and reboot the machine. You need to use a serial terminal application to communicate with the machine; a good option on a &debian; GNU/Linux is to use the cu program, in the package of the same name. Assuming the serial port on your computer is to be found on /dev/ttyS0, use the following command line: cu -lttyS0 -s115200 If using Windows, you may want to consider using the program hyperterminal. Use a baud rate of 115200, 8 bits word length, no stop bits, and one parity bit. When the machine boots, you will see the following line of output: No network interfaces found EM-7210 ver.T04 2005-12-12 (For ver.AA) == Executing boot script in 1.000 seconds - enter ^C to abort At this point, hit Control-C to interrupt the boot loader Note that you have only one second to do so; if you miss this window, just powercycle the machine and try again. . This will give you the RedBoot prompt. Enter the following commands: load -v -r -b 0x01800000 -m ymodem ramdisk.gz load -v -r -b 0x01008000 -m ymodem zImage exec -c "console=ttyS0,115200 rw root=/dev/ram mem=256M@0xa0000000" -r 0x01800000 After every load command, the system will expect a file to be transmitted using the YMODEM protocol. When using cu, make sure you have the package lrzsz installed, then hit enter, followed by the ~< escape sequence to start an external program, and run sb initrd.gz or sb vmlinuz. Alternatively, it is possible to load the kernel and ramdisk using HTTP rather than YMODEM. This is faster, but requires a working HTTP server on the network. To do so, first switch the bootloader to RAM mode: fis load rammode g This will seemingly restart the machine; but in reality, it loads reboot to RAM and restarts it from there. Not doing this step will cause the system to hang in the necessary ip_address step that comes next. You will need to hit Ctrl-C again to interrupt the boot. Then: ip_address -l 192.168.2.249 -h 192.168.2.4 load -v -r -b 0x01800000 -m http /initrd.gz load -v -r -b 0x01008000 -m http /zImage exec -c "console=ttyS0,115200 rw root=/dev/ram mem=256M@0xa0000000" -r 0x01800000 Where 192.168.2.249 is the IP address of the installed system and 192.168.2.4 the IP address of the HTTP server containing the kernel and ramdisk files. The installer will now start as usual.
