Hello Johnson, JL> I've tried to replace HIMEM64C/EMM38664 instead of FDXXMS/UMBPCI and JL> during test I crash the PC with following configuration:
JL> device=c:\freedos\emm38664.exe JL> devicehigh=c:\freedos\udma.sys (ver 6.8, loading low this can pass) The problem here is, that loading UDMA high in a EMM386 environment requires VDS support, because UDMA passes a command block to the DMA chip, and needs physical adresses to do that (instead of logicals) I didn't check, if the required VDS subfunctions, that are used by UDMA, are implemented by EMM386(64) try device=c:\freedos\emm38664.exe VDS VDS support is disabled by default, because it's implementation is a) incomplete b) very little tested. c) currently causes more trouble then it solves. if that works - fine. if not, load UDMA low. tom ------------------------------------------------------- The SF.Net email is sponsored by EclipseCon 2004 Premiere Conference on Open Tools Development and Integration See the breadth of Eclipse activity.
