I just decided to put in and try a VGA adapter in my PC-XT.
However i have no idea about if each ISA slot have dedicated memory space. If the VGA card require i use special memory adresses (ISA slot).
If the OS DOS 6.22 look for VGA card in a special memory space etc.
My computer have a vertical add onboard mounted on motherboard with 4 8-bit isa slot. I did put the VGA board in the second slot from top and put on the pc, the CGA/MGA 9-pin adapter still show picture. Is this normal or will it switch to VGA once VGA drivers detected in DOS.
I do not dare to put my LCD into the socket quite yet i will try get hold of an older monitor.
But if anyone have configuration tips regarding ISA slot, motherboard jumpers, VGA-card switches and eventual DOS configuration of VGA space, i am all open ears.
