I have a board ('96) that doesn't do any dma, but accepts to be set to pio 4, dma 2. This results in several crashes per day, corrupt data on ro filesystems and so on.

I have a board ('96) that doesn't do any dma, but accepts to be set to pio 4, dma 2. This results in several crashes per day, corrupt data on ro filesystems and so on. Changing wd to 0xffc (pio 4) does fix it. Tobias

With very bad results on my files. What parameters are you trying to change? Why do you think it will have ANYTHING to do with fixing your crashes? The disk's parameters are what they are. The disk knows what they are, the OS asks, the disk responds. The OS reports and utilizes them. Other than the DMA and PIO modes, there isn't much to change. Yes, crashes are bad on lots of things. Altering the disk parameters is bad in much the same way...you will just add problems, not fix them. Nick.
