It is the byte at offset 8 makes me questioning. It is the revision
identification register. This machine has a 945PL nb. According to
Intel's doc(945x specification update 307503-010), the register should
have a value of 82. Am I making mistake?

BTW, is the 0xe7 byte, with a value of '98', the same byte as the
'reg8' in the following excerpt of v3/northbridge/intel/i945/stage1.c?

static void i945_detect_chipset(void)
{
	u8 reg8;

	printk(BIOS_INFO, "\n");
	reg8 = (pci_conf1_read_config8(PCI_BDF(0, 0x00, 0), 0xe7) & 0x70) >> 4;
