SYMPTOMS
The screen display on your AT&T 6300 doesn't write to or clear the screen correctly. Common problems include the following:


 * Failure to write to the screen correctly (using DIR, and so forth).
 * Failure to clear the screen correctly (using CLS).
 * MS-DOS Shell fails to display or displays incorrectly.

Both text-based screen writes and clear screen commands affect only the top half (1/2) of the screen. Most applications work correctly, but from the MS-DOS command prompt or inside MS-DOS Shell, the screen may not update correctly.



CAUSE
AT&T has confirmed that these problems occur under ROM BIOS versions earlier than 1.43.



RESOLUTION
According to AT&T, if the ROM BIOS version is earlier than version 1.43, then you should upgrade to ROM BIOS version 1.43 to solve these problems.

Customers can order the BIOS update though AT&T's National Parts Hotline at (800) 222-7278 ([800] 222-PART). The 1.43 ROM BIOS part number is 105-203-780.

The products included here are manufactured by vendors independent of Microsoft; we make no warranty, implied or otherwise, regarding these products' performance or reliability.
