Please further advice. I purchased for my controller board with LPT port, MosChip MCS9865 chip and sellers at the same time I sold the installation CD-ROM with drivers. I would like to do a silent install, but it fails. Type switch / S / passive / qn like this do a silent install. Please help me find a suitable switch or bat file to install. Manufacturer controllers me so far on my question answered. Have a nice day and well-being wishes Zdenek
Thanks for the suggestion, but does not want to work in WIN81_x64!. Again I wrote to the manufacturer for advice, but still waiting for his answer.
