Wrong keyboard language in MS-DOS 7 all of a sudden

Hi,

I switched out the motherboard in my Pentium MMX PC running Windows 98 SE and MS-DOS 7.

Everything was working fine including in MS-DOS, but now all of a sudden some of the keys on my keyboard are mapped incorrectly.

I'm on a Swedish keyboard and I'm using the same configuration as I've always used:

mode con codepage prepare=((850) c:\dos\ega.cpi)
mode con codepage select=850
keyb sv,,c:\dos\keyboard.sys

This has always worked in MS-DOS, including after switching out the motherboard, but when I booted the PC today some of the keys seemed to have the wrong mapping.

Any ideas?

which keys do you refer to?
when you type Y, what do you get?
when you type Z, what do you get?
when you type shift-8, what do you get?
what do you get when you hit the key right of P?
what do you get when you hit the keys right of L?

does keyb approach when you type
mem /c /p

what do you get when you type
chcp

On the Swedish keyboard layout, the left bracket key is mapped to "å" and the right bracket key is mapped to "¨" (with "^" and "~" accessed via Shift and AltGr respectively).

Both of these keys work fine when pressed without modifier keys (i.e. they output "å" and "¨" as expected), but when combined with AltGr, left bracket outputs a left bracket even though it's supposed to output nothing, and the right bracket outputs a right bracket even though it's supposed to output a tilde ("~").

So basically, the keyboard layout behaves like a Swedish keyboard layout, but the left- and right bracket keys behave like they do on an American keyboard layout only when AltGr is used as a modifier key.

"y", as expected.

Left parenthesis ("("), as expected.
