## 9.4. When all else fails...

Some other VLB boards can only map the linear framebuffer above the 1GB mark (0x80000000 and up), so you must use a MemBase that is higher or equal to 0x80000000.

Some other VLB boards can only map the linear framebuffer BELOW the 16 MB mark. So you may want to try booting your system with up to 12 MB of memory (some operating systems allow you to supply a boot-time parameter that limits the memory to a certain amount, so you don't have to open your computer to try this), and set the MemBase to 0x00C00000 (=12M).

Unfortunately, there is no easy way to tell what system you have (these details are mostly not in the motherboard manuals). Trial and error is the only road to success here. The server code will provide a default that works on most boards... but yours won't be one of those, of course.
