That's interesting. I missed that detail. Back in the 90s I could consider myself the master of all gimmicks related to Mode 13h. I skipped the whole Mode 12h (hires) because of that 16 colors limit and SVGA was much more convenient already to provide the same hires with 256+ colors and backward compatibility how to treat it (indexed colors went through the same palette encoding and framebuffer was available at the same address, it was only bank-switched due to 64kB address space limitation in 16bit real mode under DOS. Then VESA 2.0 fixed it all with 32bit protected mode linear frame buffer for any supported resolution.
