5.222. TASK SWITCHER API PATCH Every program that uses Bulld Notification Chain (INT 2FH, Function 4B01 HJ or Hook Notification Chain (Service Function 0004H) must check for and Install this patch each time the Task Switcher calls Query Suspend (Notification Function 0001 H). Without the patch, the Task Switcher behaves e"atlcally and may lose data. The problem occurs because the Task Switcher Inadvertently clears the CX register, which may affect subsequent DOS system functions. Programs can check tor and Install the patch by executing the Patch Swapper routine given below. On entry, the client program must make sure the ES:DI registers point to the Task Switcher's service-function address. This Is the same address provided by the Task Switcher when It calls Query Suspend. OldCode Newcode

• If Buffer_Head- Buffer_Tall, the buffer Is amply,

• Two bytes are necessary to store each keystroke, because the IBM extended keys (F1 •F1 O, for example) consist of 2-byte codes. If the first byte for a keystroke Is nonzero, then It represents the ASCII key, and Iha second byte Is zero. If the first byte la zero, than It represents an extended key, and the second byte Indicates the actual key pressed. • Two low-memory words store Iha location of the buffer start (at 0040:0080) and one byte past Its end (at 0040:0082). •Ona standard PC, the keyboard buffer Is usually localed at 0040:001A.

*720x400 on VGA tVirtual resolution is 1056 by 200, 350, or 400 scan lines. Each character is a pixels wide. Character height depends on font used. ¥XGA supports all VGA modes, but only works on 386 or 486 machines. Note:

• EGA figures assume it has a full 256K of RAM. • Modes 8-12 are used by PCjr only. • The default XGA mode is VGA. XGA also supports special non-BIOS modes via the HSMODE function, with the following new modes available:
