In 1982, Compaq introduced the first true IBM PC clone, the Compaq Portable, which was also portable but weighed 28 pounds. It featured a reverse-engineered IBM BIOS for near 100% compatibility with IBM PC applications. The Compaq Portable's success kick-started the PC clone industry and inspired a new era of PC enthusiasts. Despite IBM's later entry into the portable PC market, Compaq's innovative product paved the way for the industry's growth.

Enthusiast fixes 30-year issue with S3 graphics card — hacking the VBIOS fixes black levels by scalpelling out the Virge DX’s ‘pedestal bit’

Enthusiast fixes 30-year issue with S3 graphics card — hacking the VBIOS fixes black levels by scalpelling out the Virge DX’s ‘pedestal bit’

A retro hardware enthusiast successfully fixed a 30-year-old issue with S3 graphics cards by hacking the VBIOS to address the 'pedestal bit' problem that caused washed-out black levels. By adjusting the hexadecimal value in the VBIOS code, the darkest blacks were restored to their proper color, eliminating the undesirable gray appearance. The enthusiast used debugging tools to locate and modify the pedestal bit, then dumped the VBIOS to a file, made the necessary tweaks, and flashed it back to the hardware. The fix resulted in a deep black background upon booting, confirming the successful elimination of the pedestal bit issue. This solution can potentially be applied to other S3 Virge DX models, offering a resolution to a long-standing problem in graphics card technology.
