Re: Linux on Bochs

Thanks for your reply. I was trying to do all that on FC9 but unfortunately my system crashed and I have installed Ubuntu now. I am new in dealing with things like setting up toolchain etc. I got gcc-4.3.2 installed when I installed Ubuntu. I am trying to build gcc-3.3.3 so that I can use that and

why would someone reinvent the kernel space read/write routines?

recently perusing someone's module code and ran across the following definitions for reading/writing either 8, 16 or 32 bits: unsigned char read8(void* address) { return *((unsigned char*) address); } and so on for read16 and read32, as well as the converse for writing. i was a b

keyboard input

How does linux handle keyboard input? I dont mean how the interrupt works, I mean where does it store the keystrokes? Is there some global buffer that it just puts them in until someone reads from it? I did some I/O programming in school, and thats how we did it, but we used the UART and never touc
