dhcp - establishes link with router or networking device and assigns an IP.Setenv bootargs console=ttyS0,115200 earlyprintk root=/dev/sde1 **copy and paste the outputs of both into the next relevant commands: $this->bbcode_second_pass_code('', 'Marvell >') You should now see the following, if not power off the device again and try again. Power on your rn104 and you will see the output of u-boot. We only need the rootfs on the usb drive as the kernel is loaded from uboot. ll/mirabox but use sdX1 as the partition NOT sdX2 as that guide gives. Turn the ReadyNas 104 off.įollow steps 2, 3, 4c, 4d, 6, 7 and 9 from here. If you use method 1, you can skip section 02, but refer to it for setting up your HDD.īefore proceeding, ensure you have connected the UART cable both to the serial port on the rn104 and a USB port on your pc/laptop and have a terminal session up ( screen /dev/ttyUSB0 115200 ). I will be using the 2nd method in this guide. Use a usb device to hold a temp archlinux rootfs to rsync to sda and also requires editing bootargs in u-boot.Swap in a HDD in pre-partitioned with the rootfs extracted on it.There are several ways you can achieve the end result. Know what your IP address is for your pc/laptop you will need this for passing the kernel and ramdisk later. If you have another, disconnect it, or swap it to the top port. Only connect 1 ethernet cable to the TOP port. Have atftpd installed on your pc/laptop, also run # mkdir /srv/atftpĤ.4.1 Generic Bootable Kernel for RN104 move this to /srv/atftp as aboveģ.3v Serial UART usb cable (ebay/amazon £4) for the kernel image and various commandsīackup, Backup, Backup! - This process is destructive to your data on sda and / or any X-RAID array (obviously) The aim of this guide is to convert from ReadyNAS OS to a self-contained Arch Linux install that boots from a /boot partition on the first drive. When using this method, you may find it necessary to disable any fan warning settings in your motherboard BIOS, since the motherboard may incorrectly believe that its CPU fan has failed when the fan is connected to a fan controller rather than directly to the motherboard itself.I am posting this for archival reasons and hopefully someone somewhere can make us of this guide to go from ReadyNas OS to a complete Arch Linux install. Several models are available now which provide 4-pin fan headers, so this is an easy way to use 4-pin PWM fans in a PC system which has only 3-pin fan headers on its motherboards. This problem also occurs if you try to use an in-line fan speed controller such as the one made by Gelid.Īnother avenue to explore is the possibility of using a bay-mounted fan controller. The only other problem to consider is that occasionally, components immediately adjacent to the motherboard fan header can get in the way of the larger 4-pin fan connector, physically preventing connection. The fan will potentially run at full speed, so if you would like to reduce the speed of the fan you will need to adjust the fan speed setting in your BIOS or use fan control software such as SpeedFan in Windows. So you can plug the 4-pin fan connector onto the 3-pin motherboard fan header, leaving the fourth pin not connected to anything. Screw hole spacings and fan sizesĮlectrically, there is no problem doing this - the fourth pin on the fan cable is used purely for PWM control and is not needed in order for the fan to run. Note that the mounting hole measurements shown below are taken horizontally or vertically between the holes and not diagonally. If you know the distance between the fan mounting screw holes but don’t know what fan size to order, please see the following table. If you have any questions about which fan you should order, please don’t hesitate to get in touch. All our fans are 25mm thick unless otherwise stated. This isn’t really dictated by customer preference, but more by recent designs of PC cases.Īs for the thickness (depth) of the fan, generally 25mm (1 inch) is by far the most common depth, although smaller fans can have shallower depths such as 15mm or even 10mm. The sizes of all the fans on our website are shown as measured along any one of the fan’s four sides, NOT the distance between the fan’s screw holes! Our most popular fan size is 120mm, followed by 80mm. The size of fan you need will generally be determined by the size of the fan fitting position in your PC case.
