Hallo, for the following: assume that es:[bx] points to a 32-bit memory mapped register. Let's say I want to set the lowest bit in that register. Else than that, I want to leave the rest of the regist...

Do any Intel Core CPU have unique ID (again)? 1 40 (6/25/2012 4:47:22 PM)
AFAIK, only Pentium 3 CPU has unique ID. Then I found a wiki article: http://en.wikipedia.org/wiki/Steam_(software) #Software_delivery_and_maintenance At last paragraph of "Software delivery and mainten...

Difference between 16, 32 and 64 bit code 5 40 (6/6/2012 1:55:08 PM)
I've done assembly programming on the 6502 and 68000 families. I've never really learned the difference between 16, 32 and 64 bit coding in the Wintel world though. The usual explanations are that ints are ...

Forcing reading and writing uncached 15 49 (5/25/2012 5:15:14 AM)
Hallo, I need to read/write memory mapped registers. Suppose the BIOS / OS has not properly marked that memory mapped range as unc-cachable (UC). Is there any instruction in the Intel instruction set s...

How does this instruction assemble ? 11 75 (5/26/2012 6:50:40 PM)
Hallo, I have to use an assembler that can only assemble <= 386 instructions (don't ask ...). I want to use instruction: movnti es:[bx],eax from a 16-bit (!) code segment. Does this assemble as: ...

unsigned/signed in asm 9 41 (6/4/2012 9:55:31 AM)
Hi How can i make sure, that an 32-Bit-Value (on a 32-Bit-System) is unsigned (positive). As exapmple : 0FFFFFFFFh : How can i make sure, that this is not -1 ? If i call a function, that allows positi...

Challenge: More Instructions in Fewer Bytes 4 31 (5/29/2012 11:49:32 PM)
Hi all, I'm sorry if this is a bit naive. Long ago, in an IRC channel far far away, the following idea for a challenge appeared: Write two versions of the same routine/algorithm where the one using mor...

bootstrap32 - now FAT32 / FAT16 / FAT12 0 27 (6/9/2012 7:08:22 PM)
bootstrap32 will now boot and run FAT32, FAT16, and FAT12. The bootstrap32 code is identical, the only difference is the Bios Parameter Block (in the boot sector) and the file system. Even the boot sector co...

How compilers implement objects in x86 assembly 10 31 (5/30/2012 11:45:31 PM)
Hi, I'm learning x86 assembly on my free time and I'm trying to find how do= es high level compilers implement classes and objects in x86 asm. So far I = saw some toy compilers that use structs, but the way I...
