These are the instructions to upgrade the Flash BIOS in your T2100CS.

(1) create a 720KB bootable DOS diskette.

(2) copy CHGBIOS.EXE, BOOTBIOS.COM, and AUTOEXEC.BAT onto that diskette.

(3) disable resume mode on the T2100CS.

(4) turn the T2100CS off.

(5) insert the diskette into the FDD.

(6) hold down the 'F12' key.

(7) turn the T2100CS on.

(8) CHGBIOS will report the BIOS version in the T2100CS, the version on the
    diskette, and then ask if you wish to proceed.  Enter YES.

(9) When CHGBIOS is done, it will ask you to press the computer's reset button.
    Don't forget to remove the diskette from the FDD, before you press reset.
