They’re just different code sections. PAGE code sections are paged at the
OS’s convenience, INIT code sections are discarded after execution. ‘page’
(not PAGE) code sections are not paged. You can use dumpbin mydriver.sys
/headers to check this - look at the ‘Flags’ for each section header.
This is likely not directly related to the problem you’re seeing. In this
specific case, I recommend commenting out all of those alloc_text() pragmas
at least until you’ve initially debugged your driver.
Although it’s not DIRECTLY related, and just for peace of mind, use dumpbin
to make sure you’re Isr() function exists in a nonpaged section. If it’s
not, that is indeed a likely cause of the bluescreen, then you just have to
determine why Isr() is getting put into that paged section…

Subject: [ntdev] RE: IoConnectInterrupt crashes in Win2000 Checked build
?
Hi,
Regarding the problem I faced earlier, I found out
something. Initially, I was making some driver
functions pagable by declaring
#ifdef ALLOC_PRAGMA
#pragma alloc_text(init, DriverEntry)
#pragma alloc_text(page, DriverUnload)
#pragma alloc_text(page, DispatchCreate)
#pragma alloc_text(page, DispatchClose)
#endif
If I declare the same functions as follows, I do not
crash in Win2k checked build.
#ifdef ALLOC_PRAGMA
#pragma alloc_text(INIT, DriverEntry)
#pragma alloc_text(PAGE, DriverUnload)
#pragma alloc_text(PAGE, DispatchCreate)
#pragma alloc_text(PAGE, DispatchClose)
#endif
Does anyone have any idea what is the difference
between page and PAGE and why I would be facing this
problem ??
Thanks for any help.
