After the release of the initial models in 1993, new models started to become available as the Presario brand grew over time. The 500, 700, and 900 series (including the 5500, 7100, 7200, 9200, 9500, and 9600 series) were introduced to compliment and succeed the original lineup, making up the first generation of Presario computers produced from 1993 to 1996, also known as "Series 1".
An option ROM for the PC platform (i.e. the IBM PC and derived successor computer systems) is a piece of firmware that resides in ROM on an expansion card (or stored along with the main system BIOS), which gets executed to initialize the device and (optionally) add support for the device to the BIOS.
Compaq produced some of the first IBM PC compatible computers, being the second company after Columbia Data Products [3] to legally reverse engineer the BIOS of the IBM Personal Computer. [4] [5] It rose to become the largest supplier of PC systems during the 1990s. The company was initially based in Harris County, Texas.
This BIOS enabled OEMs to build essentially fully compatible clones without having to reverse-engineer the IBM PC BIOS themselves, as Compaq had done for the Portable; it also helped fuel the growth in the PC-compatibles industry and sales of non-IBM versions of DOS. [69] The first American Megatrends (AMI) BIOS was released in 1986.

At the time when these boards were in ...

Aside from using DOS 1.x, the initial Portables are similar to the 16 KB – 64 KB models of the IBM PC in that the BIOS was limited to 544 KB of RAM and did not support expansion ROMs, thus making them unable to use EGA/VGA cards, hard disks, or similar hardware. After DOS 2.x and the IBM XT came out, Compaq upgraded the BIOS. Although the ...
