Desc: the low word of this vector contains the segment of the RAM data area to be used by the expansion ROM at F400h:2000h, and the high word contains the length of the data area; this segment and size are both set to 0000h if no ROM is installed at F400h:2000h SeeAlso: INT 61"TI Professional PC",INT 63"TI Professional" SeeAlso: INT 66"TI Professional PC" --------b-62--------------------------------- INT 62 - HP 95LX - USED BY CALCULATOR SeeAlso: INT 60"HP 95LX" ----------62--------------------------------- INT 62 - MS SQL Server/Sybase DBLIBRARY interface - ???

Note: the installation check consists of testing for the string "DBLIBRARY" 2 bytes past the interrupt handler SeeAlso: AH=08h"SQL" Index: installation check;MS SQL Server|installation check;Sybase DBLIBRARY ----------62--------------------------------- INT 62 - MPAUSE - ??? details not yet avialable Program: MPAUSE is a program by Manfred Michael which appeared in the German _EGA-Handbuch_ from m&t-Verlag --------N-62--------------------------------- INT 62 - XFS v1.76 - FILTERED PACKET DRIVER API Program: XFS is a shareware Network File System client by Robert Juhasz Desc: XFS requires a packet driver to operate. Since it does redirections, etc., it provides its own packet driver entry point, changing the signature string of the original packet driver to "XKT DRVR" so that it will no longer be found by the packet driver installation check Range: INT 61 to INT 66, selected by scanning for two consecutive free vectors and hooking the second Note: the installation check for this vector is the same as that for the packet driver specification: scan for the signature string "PKT DRVR" three bytes past the interrupt handler SeeAlso: INT 60"Packet Driver",INT 61"XFS" ----------62--------------------------------- INT 62 - PC-DRAFT - PRIMARY DISPLAY DRIVER ???
