Johnson Lam has posted a new DRIVERS.ZIP dated 24-Feb-2012 on his website at <http://johnson.tmfc.net/dos/drivers.html>.
In it, UIDE and UIDE2 are corrected so that they again handle "64K UltraDMA boundaries" properly. A user I-O buffer which crosses-over a 64K address boundary will cause the drivers to move output data to, or input data from, their own XMS buffer which is aligned with NO boundary and will handle actual I-O. Like I wrote before on this forum, note that I "suspect" this problem may affect only "old" year-2000 and earlier chipsets, since the previous UIDE/UIDE2 have not given any "big number" of data errors for users! But I want the UIDE drivers to be compatible with ALL UltraDMA controllers, so they are fixed! Also, UIDE/UIDEJR are a bit smaller and UIDE2 is MUCH smaller due to my "experiments" in writing a 7K-byte version of UIDE2 for my "backup/restore" diskettes. My run-time driver logic is "good", but my driver initialization logic is often "quick and dirty" since it disappears after the driver loads! That has now been remedied, very much so in UIDE2! A minor error -- I "date stamped" XMGR/UIDEJR in the files on Johnson's website to 2-24-2011, not 2012! A "typing error" by me, which Johnson shall correct. XMGR/UIDEJR do show the year "2012" in their title messages, and they do work fine! ------------------------------------------------------------------------------ Keep Your Developer Skills Current with LearnDevNow!
