I'd prefer that to another funciton. >Something like `isa_dmastart(B_WRITE|DMA_BLOCK, .....);', maybe? Definitely, I think it would only require at most 20 lines of code in the isa_dmastart() function... I could post the hack if necessary. I did write the isa_dmastart_blk() function in order to not interfere with other device drivers, I have been rebooting my PC probably 100 times these last days ! Emmanuel
