DOS ain't dead - preliminary Jemm v5.68 (includes XDMA32 with SATA support)

preliminary Jemm v5.68 (includes XDMA32 with SATA support) (Announce)

Hello,

a preliminary new Jemm version is available, which contains a new JLM, XDMA32, an Ultra-DMA HD driver.

XDMA32 is based on J.R. Ellis' XDMA v3.3. SATA support has been added and some bugs were fixed. Most BIOSes nowadays support Ultra-DMA, but according to Mr. Ellis there exist some ("El Cheapo"), which virtually disable this support when running under a v86-monitor like Jemm. In such cases XDMA32 might give a significant speed boost. The driver needs just 32 bytes of DOS memory.

The creation of XDMA32 revealed a bug in JLOAD - the DMA locking function did ignore a flag to check for 64 kB border crossing -, so there was a need to update Jemm to make XDMA32 run.

WARNING: This version is preliminary, intended for testing only! If XDMA32 is installed, it becomes a very crucial system component which might cause data losses if it's not working correctly!!!
