Quadram QuadEGA+

I'm looking for anyone with experience using an EGA in 43 line mode.
We are using a Quadram QuadEGA+, and the IBM technical reference, and
after calling the BIOS in the manner specified by IBM, we see:
o The 8 by 8 character set loads fine.
o The display *appears* to be in 43 line mode (line 24~= 2/3 down)
o When we scroll down to line 24, the display does not scroll up.
o We cannot move the cursor to any line below 24.
o Examination of absolute location 0:484 (rows) shows 0x2B (43 lines).
My question is this: Is it us, Quadram, or both? We have called Quadram,
and they say, "The QuadEGA is 100% compatible .... Lotus runs fine in 43
row mode .... we can't provide that type of support (BIOS discussion)".
In short, Quadram technical support is useless.
Any help, phone, net or email, would be greatly appreciated.
Thanks in advance,
John Allen

I have a QuadEGA+, and it works fine in 43 line mode. I have have tried
it with nansi.sys, as well as with the following program from PC Magazine.
The following is a debug script that puts an EGA into 43 line mode.
N EGA43.COM
MOV AX,1112 ;Load 8x8 font
MOV BL,00
INT 10
SUB AX,AX
MOV DS,AX
PUSH [0487] ;Save INFO byte
OR BYTE PTR [0487],01
MOV CX,0600 ;Set cursor size
MOV AH,01
INT 10
POP [0487] ;Restore INFO byte
MOV DX,03B4 ;Fix up underline
MOV AX,0714
OUT DX,AX
INT 20
R CX
28
W
Q
Perhaps you might want to compare this to the info given in the IBM tech
manual.
