call ds:__imp__FindresourceA@12
This is grabbing a handle to a resource string from RCData with the name "UPROMPT" (you can see this in resource hacker) ... please note it'll follow by using "LoadResourceA" to actually get the string value and put it into EAX
0xA = 10 = RT_RCDATA = Application-defined resource (raw data)
0 for hModule = use this current executable's resources
pointer to the resulting string is put into eax
