if i modify the pcisetup utility to read and write
val = inb(extctrl_addr);
printf("val => 0x%x\n",val);
outb(0x80,extctrl_addr); // set for EPP mode
printf("wrote 0x80 to 0x%x\n",extctrl_addr);
val = inb(extctrl_addr);
printf("val => 0x%x\n",val);
i get
val => 0x35
wrote 0x80 to 0x77a
val => 0x85
and i notice that "$ cat /proc/sys/dev/parport/parport0/modes"
shows no epp mode available
PCSPP,TRISTATE,COMPAT,ECP
does that mean hardware that requires epp mode will not work
thanks
richard
