DEVICE.COM
my attempt to reverse engineer DESQview's DOS driver loading tool DEVICE.COM
Files:
| File | Info |
|---|---|
| DEVICE.COM | Original DESQview DEVICE.COM DOS tool |
| DEVICE.idb | IDA 6.5x IDB |
| dv.asm | reversed and reassemble-able source code of DEVICE.COM |
| build.bat | builds dv.asm with TASM32 and UASM64 and checks if resulting dv.com is binary identical to DEVICE.COM |
| tools_howto.txt | how to get the needed build tools (UASM, WLink) very easy to install |
tools_dir variable in build.bat needs to be set to suits your environment
using IDA
- add more information to the IDB
- produce ASM file in IDA (called DEVICE.asm)
- merge changes of DEVICE.asm into dv.asm
- test if resulting dv.com is equal to DEVICE.COM using build.bat
TODO
- fully revese and document the original
- replace with Borland C version
