I just got my hands on a 400 Mhz PII with 440BX chipset (100 MHz bus and SDRAM, of course). pcisupport.c 1.62 doesn't recognize the 440BX chipset, producing Probing for devices on PCI bus 0: chip0: <Host to PCI bridge (vendor=8086 device=7190)> rev 0x02 on pci0.0.0 chip1: <PCI to PCI bridge (vendor=8086 device=7191)> rev 0x02 on pci0.1.0 I made the following patch to recognize the 440BX chipset: *** pci/pcisupport.c.orig Fri Mar 27 21:36:54 1998 --- pci/pcisupport.c Thu Apr 30 21:54:06 1998 *************** *** 214,219 **** --- 214,225 ---- return ("Intel 82371AB USB host controller"); case 0x71138086: return ("Intel 82371AB Power management controller"); + case 0x71908086: + return ("Intel 82443BX host to PCI bridge"); + case 0x71918086: + return ("Intel 82443BX host to AGP bridge"); + case 0x71928086: + return ("Intel 82443BX host to PCI bridge (AGP disabled)"); case 0x12378086: fixwsc_natoma(tag); return ("Intel 82440FX (Natoma) PCI and memory controller"); The machine is (not unexpectedly) rather fast.
