- **Sappy Gushing on**
- When I first heard about Linux about a year ago, it sounded
- (as an outsider) like Linus was doing a solo. I got involved
- back in July after getting a decent new machine and I currently
- see Linux as an incredibly successful international project
- with many builders.
- I'd just like to echo the many accolades we regularly see
- and express my thanks to the many many contributors.

- I figure it's good enough news to let the world know.
- It's feasible to patch the binary X386 image to get things
- to work with the Wonder Plus set of cards. I've copied one
- of my recent mailings below. Ric Faith has incorporated the
- tweak into the XFree86 sources so it should be in the next
- release. However, I'm presuming that won't be for a little
- while. Meanwhile, you can apply the fix to the binary directly.
-
- Ok, I have yet another data point for my patch. Martin Rex informs
- me that (not surprisingly) the location is different for the
- two versions of x11 v2.0 and v2.1. I've repeated my message to Martin
- below with part of his response inserted. Use whatever means you have
- to do the byte patch. Just make a backup copy of X386 to be safe.

- The byte that needs changing is offset 0xbf4dc, I believe.
- Change the 0x28 there to a 0x31. I've never patched binaries
- before so I have no idea if this will work.

- From: mrex@aix01.rz.fht-mannheim.de (Martin Rex)
- Ok, your patch was for the binary of x11_v2.0, the offset is different
- for xfree86_1.1 (=x11_v2.1). If you search for the byte sequence
- 00D9280187 in the X-Server binary "X386", then you find the right
- location in both Versions.
-
- locate in original Code: 00D9280187
- ^^
- replace sequence with this: 00D9310187

- You should also setup your clocks in the Xconfig as in the following.
