Hi Edward,
I found a slight (but perhaps significant) difference in hardware
configurations, and here's how you fix that.
Find uc_after_set_var() in unichrome.c
Add the line marked with ++ below (except the ++ themselves of course).
(I removed the code comments for clarity.)
static void uc_after_set_var(void* drv, void* dev)
{
UcDriverData* ucdrv = (UcDriverData*) drv;
VGA_OUT8(ucdrv->hwregs, 0x3c4, 0x1a);
VGA_OUT8(ucdrv->hwregs, 0x3c5, VGA_IN8(ucdrv->hwregs, 0x3c5) & 0xbf);
++ VGA_OUT8(ucdrv->hwregs, 0x3c5, VGA_IN8(ucdrv->hwregs, 0x3c5) | 0x4);
}
Does it help?
If you still get the same problem, please verify that the change took effect
by running the hwinfo script.

The number 1A (3rd from the left on line 2) should now be 1E.
