>Description:
My Note PC is Toshiba Satellite 2550X

I installed NetBSD-1.4.1 and update NetBSD-current by "make build".
My Note PC works fine for me Under NetBSD-1.5S.

Last week,To change Disk Partition Size, I do "Fresh install" with
NetBSD-1.5T.

Then, I have a problem that "pciide0:0:0 lost interrpt".
I searched current-users and found next articles.

Thanks a lot "Araki Ken" and "Urban Boquist" for fix this problem.

From "Advanced Configurration and Power Interface Specification"
	"Rev 2.0 July 27,2000"
	"9.3.2 BIOS Initialization of Memory. page 236"

   640K - 1MB (0x9fc00 -- 0xfffff) 
   Compatibility Holes. 
	Holes within memory space that allow access to be
	directed to the PC-compatible frame buffer (A0000h-BFFFFh),
	to adapter ROM space (C0000h-DFFFFh), and to 
	system BIOS space (E0000h-FFFFFh).	
	
I think it need avoid compatibility holes "0xa0000 - 0xfffff".
