That is true of ATX based motherboards with supporting OS using all
features. About your CGA card, it have this caused by direct access
to video RAM during video scan, sometime causes "snowing". It use
IRQ to disable this part by doing all memory work during flyback
retrace but makes this more slower. But if you change the card for
EGA or 3rd party EGA setup to use EGA and below and also set the card
to drive CGA display. Fast and no snow. Many old ATI wonder series
has dual 15 and 9 pin ports, you can also use this in the XT bus and
can drive anything up to EGA emulation and nice feature some of them
has bus mouse on it. Try ET1000 and ET2000 they are fastest old
video cards and no snow but I have yet to see one, Yes I have seen
ET3000 and up.

Snip!
