I searched quite a lot on the Internet without finding quick and easy information, since it seems that everybody is assuming that at least from first boot you do have monitor connected, then you need to enable serial console.

I managed at least to start an installation with CentOS 5.1, by doing the following:

  • Check that in BIOS you have enable the USB CD-ROM booting
  • Check in BIOS for Serial Console redirection enabled, set in my case at 9600 bps
  • Check in BIOS for Serial Console Agent to remain also after boot. If this is not set initial boot seem to happen but then booting process continue somewhere else than on serial console (lost 5 hourse before discovering this)

Once you arrive at CentOS boot prompt, you need to instruct Linux to boot with text based installation and using serial console. Correct boot string is:

linux text console=ttyS0, 9600, n, 8, 1

Installation will start and after selecting the language to use you are prompted for where installation must be executed from.

Select Local CD-ROM but if you are using USB external CD-ROM, then you have to choose Select Driver and then USB Mass Storage driver for Linux (usb-storage) to have Linux recognizing the external drive.

Once you do this installation will go on.

This is just the beginning, more to come… as soon as I’ll be able to finish the installation 😉

Update of 22.00, same day: Installation ended… and my appliance is working with CentOS5!

Oh, Yeah!!!
