这两天要做个DOS软盘镜像，用Winme DOS8.
为提高磁盘性能,以前一直用SMARTDRV(Datalight SMARTDRV v6.22 (Revision 4.20.1588SU),也非常耗内存,大约40K.
使用FreeDOS下lbacache.com,兼容性又不太好.
终于看到UDMA.

有人说UDMA是DMA磁盘驱动, 可文档上说是缓存程序
***************************************************
UDMA is a DOS hard-disk caching driver.
......
All possible I-O for SATA and UltraDMA disks goes through its XMS cache buffers, for
faster speed. UDMA calls the BIOS for diskettes and other type disks,
so it will cache ALL disks on a DOS system!
果真如此,使用它来代替SMARTDRV,那可是太妙了.
