Using a BIOS Floppy Disk

If you do not have a BIOS floppy disk, download the package from the Partnership Web site (see page vii) under Product Support Information in the Service and Support Library. Follow the instructions for creating the BIOS floppy disk.

Caution

Make sure to use the correct BIOS floppy disk for the notebook model you are repairing. The program does not verify the notebook model, so you could accidentally install the wrong BIOS.

1.Insert the BIOS floppy disk in the floppy disk drive.

2.Turn on the notebook and allow it to boot from the BIOS floppy disk.

If the notebook does not turn on at all, do the following to boot from the BIOS floppy disk:

a.Unplug the AC adapter.

b.Press and hold Fn+B

c.Plug in the AC adapter.

d.Release Fn+B.

Note

If the notebook will not boot from the BIOS floppy disk, try plugging the boot-block jumper into the notebook’s parallel port. See the wiring diagram below.

3. The display goes blank for a minute or more while the BIOS is reprogrammed.

Note

If you plugged in a boot block jumper, unplug it before the notebook automatically reboots.

4.After the BIOS reprograms itself, check the BIOS version to make sure it is the latest version. If necessary, download the latest BIOS version and reprogram the BIOS IC.

2500, 2100, 1100 specifications

The HP 1100 and 1100A are pivotal laser printers developed by Hewlett-Packard in the early 1990s, marking significant advancements in printing technology of their time. Since their introduction, these models have garnered a reputation for reliability and efficiency, making them a staple in many offices.

One of the standout features of the HP 1100 series is its fast printing speed. The printers can produce up to 12 pages per minute, which was an impressive feat at the time of their release. This speed significantly reduced waiting times, allowing users to handle large-volume printing jobs with ease. Furthermore, the printers support a variety of media types, including letterhead, envelopes, and labels, enhancing versatility in print applications.

The HP 1100 and 1100A utilize laser technology, which ensures sharp and high-quality prints. The printers have a native resolution of 600 x 600 dots per inch (DPI), enabling crisp text and detailed graphics. This high-resolution output made the models particularly favored for producing professional documents and presentations.

Another key characteristic is the generous memory capacity. The HP 1100 typically comes with 2 MB of standard RAM, which is expandable, allowing for improved performance in handling complex print jobs. Users can adjust the memory according to their requirements, resulting in better efficiency, particularly in environments that demand high-volume printing.

The HP 1100 series also showcases a straightforward and user-friendly operation. The built-in control panel simplifies the printing process, allowing users to manage jobs intuitively. Additionally, with the inclusion of parallel and later USB connectivity options, integration with various computer systems was seamless, ensuring compatibility with existing office infrastructure.

Energy efficiency is another aspect worth noting, as the printers are designed to consume minimal power when idle, aligning with the growing demand for eco-friendly solutions.

Overall, the HP 1100 and 1100A stand out for their robust construction, high-speed performance, exceptional print quality, and user-friendly features, making them a trusted choice for small to medium-sized businesses in need of dependable printing solutions. Their impact on the printing landscape during the 1990s continues to be felt today, as they paved the way for subsequent generations of laser printers.
