A site where discontinualed schematic diagrams and back dated information can be found on discontinued radios tv's and any electronic equipment can be found. Newer manuals either Service and operating manuals. Radio amateurs should find this site a great source for ham radio equipment manuals. I will return to this site should I need information on any electrical equipment. priced easy to download in a PDF format and print pages need to undertake the repair.

Quality scan of the original. All the detail necessary to troubleshoot, repair and adjust the unit. I'm sure I will be downloading more manuals in the future as the need arises.
;
Exactly as described, a Service Manual complete with the schematics and PCB layout delivered in a timely manner. Many thanks for the great service.

Well.. I'd searched for this manual and although I found many copies online I was pleased to find your website with a well balanced pricing system and easy to search and follow links. That together with the very quick response time was just what I was looking for.. being a very impatient tech.. ;-) I had the service manual in front of me within a short time.
Bookmarked.. and you can bet I will always come here first for my service & user manuals..
best regards

Overview of BIOS Features
3.9 USB Legacy Support
USB legacy support enables USB keyboards and mice to be used even when no operating system USB drivers are in place. By default, USB legacy support is disabled. USB legacy support is only intended to be used in accessing the BIOS Setup program and installing an operating system that supports USB. This sequence describes how USB legacy support operates in the default (disabled) mode. 1. When you power up the computer, USB legacy support is disabled. 2. POST begins. 3. USB legacy support is temporarily enabled by the BIOS. This allows you to use a USB keyboard to enter the BIOS Setup program or the maintenance mode. 4. POST completes and disables USB legacy support (unless it was set to Enabled while in the BIOS Setup program). 5. The operating system loads. While the operating system is loading, USB keyboards and mice are not recognized. After the operating system loads the USB drivers, the USB devices are recognized. To install an operating system that supports USB, enable USB Legacy support in the BIOS Setup program and follow the operating system�s installation instructions. Once the operating system is installed and the USB drivers configured, USB legacy support is no longer used. USB Legacy support can be left enabled in the BIOS Setup program if needed. Notes on using USB legacy support: � � � If USB legacy support is enabled, don't mix USB and PS/2 keyboards and mice. For example, do not use a PS/2 keyboard with a USB mouse, or a USB keyboard and a PS/2 mouse. Do not use USB devices with an operating system that does not support USB. USB legacy is not intended to support the use of USB devices in a non-USB aware operating system. USB legacy support is for keyboards and mice only. Hubs and other USB devices are not supported.
