Ok guys. I have an old computer that I’m hoping to upgrade to act as an Internet Gateway/Firewall using FreeBSD. I have a few questions about old technology though. The motherboard has four 72pin SIMS and I’m hoping to by some second hand ram of EBAY (I look for tested ram) that upgrade the ram to 64. This is all well and good but is it generally supported by older hardware, or is this just a matter of upgrading the bios if there are any conflicts. To bad, I don’t know what the motherboard make is so I can’t tell you much information about bios etc. I’m also hoping to buy a second hand CPU from EBAY (again tested by seller) and my socket type is an old socket 7. The current CPU is a Pentium-S 70mhz, would I just be able to simply upgrade the CPU to say a 300mhz AMD CPU, or is it intel only supported. I have also added a Voodoo 2 to the PCI slot which is linked to the old video card, would the PC be able to run of the Voodoo 2 on it’s own or does it require a proper graphics card to be installed. I’m also hoping to add USB support, which PCI card is best suited to this and is there any bios conflicts? I already have an Ethernet card for networking, just would like the support for a USB mouse because the modem will be using the serial port (I know, no PS2 mouse port it’s so old). And last but not least, Flashing? Ill get the motherboard information soon but is it easy to flash, backup current setting etc, all information is welcome. Forgotten what the last bit was .
