和emm386应该用/b参数,和umbpci用/w参数。 XMGR is a DOS driver that works as an XMS memory manager. It supports V3.70+ UMBPCI by Uwe Sieber. After UMBPCI enables upper-memory, XMGR can load there directly and provide both upper and XMS memory for a DOS system. XMGR uses an "I/O catcher" with UMBPCI, to intercept diskette or hard disk I/O above 640K. Such I/O is done through a low memory area, to avoid DMA trouble in UMBPCI "Shadow RAM". XMGR also supports V4.49 and V4.95 EMM386 (MS-DOS V6.22 or V7.10). With JEMM386, XMGR using its /B switch can first "boot" into temporary space. After JEMM386 enables upper-memory, XMGR loads there with no /B switch, copies all its "boot" data, and takes-over XMS work. Only its XMS "Handles" table stays in low memory, so EMM386 can always find them at fixed addresses. For a small XMS-only system, XMGR can also load entirely in low memory.这是说明。作者: asqw101451 时间: 2015-7-22 04:58
xmgr和umbpci连用使用i/o catcher,这个只有/w参数有此意义作者: asqw101451 时间: 2015-7-22 13:49
