I generally consider mixing 486s and PCI to be somewhat blasphamous, but I just stumbled across an interesting little board based on the UMC UM8881F chipset. I guess it's generic, and it's footprint is only half Baby AT. Before I waste some money on hardware, I want to confirm a few things about this particular chipset.
From what I understand, UM8881F is one of the few chipsets that can handle EDO memory. Is it true?
Most PCI 486 boards only do PCI 2.0, but supposedly there are a few that can do PCI 2.1. Does UM8881F support this feature?
I am also considering installing USB 1.1 and/or IEEE 1394 on this machine, but as PCI slots are few (just 3) it would depend on whether or not booting from a 1394 device is possible. 486 board definetly don't support this in the BIOS. Are there any IEEE 1394 cards that come with a boot ROM?
Assuming I can't boot from IEEE 1394, I'd prefer not to waste the slot and instead use it for something more useful like a SCSI controller. In that case, my system configuration should look like this:
am5x86-133 (possibly overclocked to 180MHz [3x60])
512kb L2 cache, 128MB RAM (possibly EDO), probably SCSI HDD and CD-ROM
PCI slot 1: ET6100 & Viper6100 w/4mb
PCI slot 2: Obsidian2 24meg SLI Voodoo2
PCI slot 3: AHA2940U2W (needs PCI 2.1)
ISA slot 1: SB AWE64G
ISA slot 2: 10/100 NIC
ISA slot 3: undecided
ISA slot 4: shared with PCI
Operating environment will be DOS and WFWG311.
Any advice or suggestions?
