Hello, I am posting this since I don't seem to be able to get through anybody decent at SCO-tech support (they say that a "senior analyst" will be calling me tomorrow). Has anyone tried the patch on page A43 of the 2.3.2 Xenix release notes ? What it is supposed to do is switch the disk controller from DMA to programmed IO. The patch is wrong since it refers to a variable in the kernel that does not exist.... I wanted to try this out since I am only getting 400Kb/second off a WD1006SR2 controller, driving a Toshiba MK134 (66MB RLL). Under DOS I am getting close to 700KB/sec.... Does anybody out there have any suggestions as to how to squeeze more performance out of this controller/drive ? BTW the system is a 386 @ 25MHz with 2Mb of main memory, and the WD controller has all the jumpers in the standard factory configuration. Thank you for your help !!!
