How can I find old bios 1.90 setup file again. ? Please help.......

You are right. On Toshiba download page you will not be able to find older BIOS version.
When the new BIOS update is realised the old one will not be available for download.
If you need older version contact nearest authorized service provider.
They must have it. Be cool and talk with them. Maybe they can send it to you per mail.
