What is TCOS?

TCOS is a new way to boot diskless (or not) obsolete computers from network based on system kernel, bins and libs (no more special compilation or patches)

Building boot images scheme with gentcos

With TCOS you can boot:

• From a lot of network cards PXE protocol
• From a Etherboot Universal floppy
• From CDROM (TCOS can build cdrom images with isolinux or grub bootloaders)
• From local hard disk (TCOS includes 2 installers, one for all system and other to install etherboot boot image)

Requisites

• A SERVER (not neccessarily a very big machine):

• Pentium IV / AMD, or Dual Core processor (in big networks you should use multiprocessor)
• High RAM (300 MB + 80 Mb * client connected) ~ 2-4 Gb RAM (with 15-25 clients)
• Almost 2 network cards in server (one for internet, and one for local thin clients)

• THIN CLIENTS

• At least Pentium 100-133 with 32-64 Mb RAM

• Can use real thin clients too, TCOS was tested succesfully with:

• EPATEC eTC2300 More info
• EPATEC eTC3800 More info
• VXL ITONA TC-6833-LI More info

NOTE If you are distributor, please contact us to test your hardware with TCOS and include here.

• NETWORK

• 10/100 Switch (if you will have more than 20-25 thin clients use two switch to better performance)
