I've done a bit testing about the parport and my ZIP. The situation stays the same even after I applied your short patch. If I turn on only EPP mode in BIOS everything works well. If I enable also ECP I can't install the ZIP. Parport itself looks happy (when I do insmod parport_pc it writes to log: "parport0: PC-style at 0x378 [SPP,EPP,ECP,ECPEPP,ECPPS2]") but the ppa doesn't :-(. I've been looking into the driver what fails: It is the second test in the ppa_init(). After w_ctr(0x378, 0xc) (I've substituted the variable with number) the r_str(0x378) returns 0x7e which has a third bit (0x08) set and so ppa thinks something is wrong. If I turn on only EPP mode in BIOS the return value of this call is 0x06 which is good... I've also printed the return values of the first test (w_ctr(0x378, 0xe)). When only EPP mode was on the return value of r_str(0x378) was 0x0e when EPP+ECP was on r_str(0x378) returned 0x7e (the same value as in the second test). Here I'm also sending you an output of id_probe:
Probing port 03bc Probing port 0278 Probing port 0378 SPP port present ECP with a 16 byte FIFO present PS/2 bidirectional port present Failed Intel bug check. (Phony EPP in ECP)
I hope this might help you. Honza.
