LG 4521B ok to flash as seconday slave?

in the readme, it says you have to make sure your drive is set to master, with no other drives on the IDE cable. is this really necessary?

with my other drives (theyre both set to master, though) i just disabled any other drives on the same IDE cable while flashing.

I have my 4163B set to Secondary Slave (with a LiteOn 1693S as Master) and flashed twice - no problem. :slight_smile:

thanks.
