[[Motherboard Configuration (New Flex)]]

*Features for new Flex [#beef24a4]

-flex is the main server of www, mail, nfs, tftp, sftp, and nis.
-flex was down because of HDD problem for every two years. 
-new flex should be a robust machine for HDD.
-new flex machine are two machines with the same systems and the same hardware.
-each HDD is backuped by Raid 0 (mirror)

*Features of new tube 2009 [#p784c6e0]

-new tube started from 2008.
-This year we will use PXE (network boot of Linux and NFS) for diskless machine.
-We will set up new tube 2009 before our setting new flex.
-new tube machine will setup as follows 
-(1) At first, we set up a new tube on the new box.
-(2) We will make a PXE server (Nugraha-san's machine?) and make a new subnet.
192.168.3.0
-(3) The PXE server, we set up tftp, dhcp, and NFS.
-(4) We try to network boot for PXE clients (new tube machine)
-(5) Finally we move to the PXE server to flex and old boxes.

*Installation Date [#f982b183]

- We set up a NIC card to Nugraha-san's Linux Machine.
- We make a subnet 192.168.3.0/255.255.255.0
- We set up dhcpd, tftpd, NFS, etc on Nuguraha-san' linux. 
- We first set up two boxes on new tube 2009
- The two boxes are connected to 192.168.3.0 subnet
- We try to do network boot on the two boxes.


*Computer Specification [#ebeb7cf0]

*Important factors to set up New Flex [#va43f196]

-Power Supply (PS) of new Flex is little bit different with other PS's  i.e. it requires 12x2  and 2 x 2 connector (power) to get power from power supply.

-We have the same PS with different connector which does not start BIOS.
-2009.4.13, Mahabubu-san and Nugraha-san found this and change PS and succeed to recognize BIOS.
