These are the instructions to upgrade the Flash BIOS in your T4900CT

(1) Copy CHGBIOS.EXE and BOOTBIOS.COM to a blank, formatted 720K diskette.
    NOTE: A 1.44MB diskette will not work.

(2) Disable resume mode on the T4900CT.

(3) Turn the T4900CT off.

(4) Insert the diskette into the FDD.

(5) Hold down the 'F12' key.

(6) Turn the T4900CT on.

(7) CHGBIOS will report the BIOS version in the T4900CT, the version on the
    diskette, and then ask if you wish to proceed.  Verify that BIOS file is
    the correct version and enter YES to continue.

(8) When CHGBIOS is done, it will ask you to press the computer's reset button.
    Remove the diskette from the FDD before pressing reset.

(9) Run TSETUP after the system reboots and check the BIOS version number in
    the upper right corner of the display to confirm that the BIOS was
    updated.
