i think it's really likely that this change needs
to be move from the kernel into 9load's sdata.c.
but it's pretty hard for me to test. regardless,
if this change is good enough for the kernel,
it should be good enough for 9load:
diff -c /sys/src/boot/pc-e820/sdata.c /n/sources/plan9/sys/src/boot/pc/
(other stuff)
/sys/src/boot/pc-e820/sdata.c:875,882 - /n/sources/plan9/sys/src/boot/pc//sdata.c:875,881
qlock(ctlr);
as = ataready(cmdport, ctlport, drive->dev, Bsy|Drq, Drdy, 107*1000);
- /* used to test as&Chk as failure too, but some CD readers use that for media change */
- if(as < 0){
+ if(as < 0 || (as&Chk)){
qunlock(ctlr);
return -1;
}
- erik
