Yes, I used memset to clear the regs variable...I am pretty sure that whatever is wrong has something to do with the pointer to the structure inside of the structure sent to the interrupt. ( whew! ) Whenever I find out what's wrong I'll let everyone know what it was. Also, if anyone is interested (and if its ok with the original author) I will post the ported CD-ROM routines once I finish them. I think that you can find cdrom_c.zip by at x2ftp.oulu.fi in pub/programming/hardware or something... John R. McCawley III Cap'n Hardgeus
