There is either a 10-pin +header (with one pin removed) on the back of the disk circuit board, +or 9 holes for you to solder in your own header. The ribbon cable +that connects from there to your serial cable or the serial port on +your computer is of the same type as used on older i386 PC's, but +be aware that there are two different types of 10-pin IDC to DB-9M +ribbon cable in use, which look identical (the differences are hidden +inside the DB-9 connector). The cable you need is wired using the +"AT-Everex" or "Asus" pinout, as described here: +http://www.pccables.com/07120.htm +and not the more straightforward to solder "crossed" type: +http://www.pccables.com/07121.htm. On the Thecus N2100, it is necessary to move jumper J3 to J4 to properly route the serial port interrupt to allow serial to work under OpenBSD. +This jumper is under the disk drives, so you may wish to ensure its +correct setting while you are installing the disk(s). For instructions +on assembling/disassembling your N2100, see the N2100 Manual at +http://www.thecus.com/download/manual/N2100%20UM%20EN.pdf Thecus cannot load a file from disk, but can load an image from flash or network. |
