Table B-24: 1st MB memory map

	Addr. range (Hex)		Device
	F0000h - FFFFFh		System ROM
	C8000h - EFFFFh		Unused
	C0000h - CBFFFh		VGA BIOS
	B8000h - BFFFFh		CGA/EGA/VGA text
	B0000h - B7FFFh			Unused

	00000h - 9FFFFh		Base memory
B.25 PCI Bus Map
	Table B-25: PCI bus map
	Function		Signals:
			Device ID	INT# pin	GNT# pin
	Onboard LAN		AD21	INT D	GNT A
	Onboard SCSI		AD20	INT A	GNT B
	PCI slot 1		AD31	INT B, C, D, A	GNT A
	PCI slot 2		AD30	INT C, D, A, B	GNT B
	PCI slot 3		AD29	INT D, A, B, C	GNT C
	PCI slot 4		AD28	INT A, B, C, D	GNT D
	Note:	In the PCA-6359VE/F, SCSI devices use "GNT B"
		signals via PCI slot 2 and LAN uses "GNT A" via PCI

slot 1. Therefore, both PCI slots cannot be used for plug-in bus master add-on cards such as a SCSI card or LAN card.
