You need this to install the “theBay” ROM as well. The process is shown online, but in short you copy the HP BIOS using a DOS/windows installer to a USB stick then copy the “theBay” rom image over the top. You could try to “dd” the image but it does some weird trickery to make the stick bootable for installing the BIOS. You can look for TheBay_Microserver_Bios_041.rar online. The source information is: http://www.avforums.com/threads/hp-n36l-n40l-n54l-microserver-updated-ahci-bios-support.1521657/ And it has all the guff on getting the BIOS onto your N54L and also tips on how to configure it. I have all the files if you need them…. Once again, these are terrific little servers. It has an internal USB port so I just loaded FreeNAS onto an 8Gb USB stick and boot from there. All the internal SATA disks are in ZFS disk pools which do my bidding. As I use ZFS, I went with 8gb ECC memory. I also added an additional Gigabit Ethernet adaptor as the built in broadcom is general networking and I run the second Gig-E port with Jumbo Frames using a gigabit crossover (there is such a thing) to a Mac Mini with the thunderbolt port running Gig-E and doing iSCSI! The Mac Mini runs esxi 5.5 and all the data stores (running various species of Linux) hosted off the HP-N54L. It is like a little tiny SAN, small but perfectly formed…. rachel — Rachel Polanskis Kingswood, Greater Western Sydney, Australia [email protected] IT consulting, security, programming The more an answer costs, the more respect it carries. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
