Unless you address it to me)I reply to all e-mail submissions, but some of my replies bounce because of bad return paths. If you don't get a response from me within a reasonable period of time, send it again with a better return path (many mailers are
improperly configured and do not produce a valid From:

THIS MATERIAL IS PROVIDED "AS IS". I verify the information contained in this list to the best of my ability, but I cannot be held responsible for any problems caused by use or misuse of the information, especially for those functions not officially documented. If it is marked "internal" or undocumented, you should check it carefully to make sure it works the same way in your version of the software (and please let me know whether or not it works the same way). Information marked with "???" is known to be incomplete or guesswork. The use of -> instead of = signifies that the indicated register or register pair contains a pointer to the specified item, rather than the item itself. Register pairs (such as AX:BX) indicate that the item is split across the registers, with the high-order half in the first register.One or more letters may follow the interrupt number; they have the following
meanings:
U - undocumented function, u - partially documented function, P - available only in protected mode, R - available only in real or V86 mode, C - callout or callback (usually hooked rather than called), O - obsolete (no longer present in current versions) The ninth column of the divider line preceding an entry usually contains a classification code (the entry has not been classified if that character is a dash). The codes currently in use are:. A - applications, a - access software (screen readers, etc),. B - BIOS, b - vendor-specific BIOS extensions,. C - CPU-generated, c - caches/spoolers,. D - DOS kernel, d - disk I/O enhancements,. E - DOS extenders, e - electronic mail, F - FAX,. F - file manipulation, G - debuggers/debugging tools, g - games,. H - hardware, h - vendor-specific hardware,. I - IBM workstation/terminal emulators, i - system info/monitoring,. J - Japanese, j - joke programs,. K - keyboard enhancers, k - file/disk compression,. L - shells/command interpreters,. M - mouse/pointing device, m - memory management,. N - network, n - non-traditional input devices,. O - other operating systems,. P - printer enhancements, p - power management,. Q - DESQview/TopView and Quarterdeck programs,. R - remote control/file access, r - runtime support,. S - serial I/O, s - sound/speech,. T - DOS-based task switchers/multitaskers, t - TSR libraries. U - resident utilities, u - emulators,. V - video, v - virus/antivirus,. W - MS Windows,. X - expansion bus BIOSes, x - non-volatile config storage. Y - security, * - reserved (and not otherwise classified) INT 00 C - CPU-generated - DIVIDE ERROR
Desc: Generated if the divisor of a DIV or IDIV instruction is zero or the quotient overflows the result register; DX and AX will be unchanged.
Notes: On an 8086/8088, the return address points to the following instruction. On an 80286+, the return address points to the divide instruction. An 8086/8088 will generate this interrupt if the result of a division is 80h (byte) or 8000h (word)
