<0> sometimes little bit of everything
<0> like at amptech we got our pcb's (the board it) made from another company
<1> where do they get their hands on these crappy ancient cpus then?
<1> no one makes them :P
<0> what crappy ancient cpu's
<0> oh you mean embedded
<0> actually they still do
<1> really?
<0> that'swhy I been studying embedded instead of x86 the last 3 yrs
<0> cause in embedded space
<1> you could still get a 200mhz intel cpu for instance?
<0> they still use a lot of 4 and 8 bit cpu's
<0> and no one gives a canuck
<0> cause it does the job
<0> well not a normal intel 200 pentium consumer
<0> but if they came out with a embedded one intel would continue making and selling fo rthta for many yrs
<0> heck they just finally stopped selling the 186 a few yrs ago
<1> you really dont need anything special just for a router
<0> and the 486EX and 386EX
<0> embedded versions
<0> yeah
<0> that's why most routers use like a $3 mips 32 bit cpu
<0> litte risc chip
<0> that's one place where risc is better than cisc
<0> embedded space
<1> im surprised it uses so little cpu power though.. it has process all the packets through a list of firewall rules, then through a list of traffic shaping rules, then route them from source to distanation.. doesn't that need a decent amount of processing power?
<0> actually most cisc chips now
<0> since the pentium pro for intel
<0> and k6 for amd
<0> are actually risc with a cisc translator
<0> ziggy sorta
<0> but it doesn'tneed video decoders
<0> floating point math for 3d, and video and sound processing
<0> so they can cut all that stuff out
<0> plus you can add a few engines to the cpu that specialize in what it's being used for
<0> like a network accelerator
<1> well im using all that.. i got medium size of list of firewall rules, then a medium size list of portforwarding rules, then a huge list of traffic shaping rules.. and it still barely breaks over 4 - 5% on the piii 600
<0> my favorite 8 bit mcu is the intel 8051
<0> it's 20+ yrs old
<0> and guess what
<0> NO ONE GIVES A FLYING CANUCK
<0> cause it stil does the job
<1> yep
<0> intel doesn'teven make the good parts anymore
<0> clone makers too
<0> do
<0> cygnal had one the size of a grain of rice
<0> it used to be the size of a standard 8086 cpu
<0> 40 pin dipp
<1> but explain to me the above
<1> <1> this--> well im using all that.. i got medium size of list of firewall rules, then a medium size list of portforwarding rules, then a huge list of traffic shaping rules.. and it still barely breaks over 4 - 5% on the piii 600
<0> yep
<0> what nics are you using
<1> i have 2 netgear's
<0> fa310?
<1> or 311.. something like that
<0> ick
<0> those are flakey
<0> but still better that GAYtek
<0> best is probably intel etherexpress
<1> eh.. had them lying around since the days when mb's didn't have onboard lan
<0> the only thing intel makes the best
<1> they work though
<0> 2nd probably dec tulip chip or clones like pnic (netgear fa310tx)
<1> what diff would i see with an intel nic?
<0> or 3com might be 2nd
<0> less cpu usage
<0> better performance
<0> depends on the bandwidth used
<0> and packets a second
<1> heh what do i care then :P im barely breaking into 5% of the 600mhz :P
<2> less dropped packets
<0> yeah in your case not much
<0> that too
<0> the better nics have some intelligence
<0> try to avoid packet loss
<1> what about the software? it has traffic shaping rules
<0> well if you are only hitting 5%
<0> obviously aren't taxing the cpu much
<1> yeah
<0> only reason I don't use a 386 or 486 for routing
<0> is the isa nics kinda ****
<0> and I hate not being able to boot from cdrom
<1> the webgui has a graphic display of cpu usage.. it stays around 2-3% and peaks at 4 or 5
<0> although with compact flash cheap nwo and compact flash to ide adaptors for $13
<0> you can boot solid state on any machine that can boot ide :P
<3> flyback2 can you please remove one of your clones from the channel
<0> oh it's my other machine
<0> lemme see if I can login to it
<0> bedroom pc :P
<1> flyback.. i have a couple isa nics laying around.. what's the diff between them ?
<0> well first isa is only 42mbit max
<0> and you will never see that much
<0> 2nd most isa nics are programmed i/o
<0> means the cpu has to sit there and feed it's mouth and wipe it's ***
<0> for the whole transfer
<0> ne2000 being the worst example
<0> whereas almost all pci nics are busmaster
<1> oh but if i transfer over the lan from pc to pc.. i wont be able to hit 100mbits with an isa nic?
<0> cpu sends request
<0> card actually does the work and dumps the packet to ram
<0> then tells the cpu when ready
<0> ziggy yes because 1st it's next to impossible to find a isa nic that even connects to 100mbit networks
<0> 2nd the cpu will max out way before the bus does probably
<1> so if i had an isa nic in that box.. my cpu would be a lot higher than 5%?
<0> isa is still good for a lot of embedded stuff though
<0> mabye mabye not depends on the load
<0> one nice thing about the old isa bus is you can just about attach wires right to the bus contacts
<0> mabye a few 20 cent 74 series logic chips to do some buffering and demuxing
<0> but pretty much almost direct wire
<0> whereas pci, usb etc need protocol interface chip etc etc
<0> for 99% of the public and servers
<0> isa, serial,parallel can die
<0> newer stuff is better
<1> heh
<4> Annes- spamming
<1> i'd actually like to have a gigabit lan here :)
<5> [20:32] <Annes-> sorry for bothering but do u ever play poker?
<6> [03:33] (Annes-): sorry for bothering but do u ever play poker?
<0> ziggy those have even more brains
<0> because at those rates the cpu gets drown in interrupts
<3> !pkban Annes- no thanks
<0> although leave to companies like GAYtek (realtek) to find a way to **** it up for cheap
<1> you dont like realtek?
<0> no
<4> http://home.comcast.net/~backpack09/1-64fastfurious.gif
<0> although sadly I need some ne2000 clone isa nics soon
<0> probably realtek chip
<6> lol S|imey cool
<1> i have 2 onboard nics on my mb in this box.. one is realtek and one is nvidia.. which do you liek better?
<0> ne2000 is the horses *** of the nic world
<0> but
<0> they have one major advantage
<0> you can attach wires to them and attach the other end to something like a mini cpu
<0> and the cpu can then have ethernet
<0> also they work well in dos :P
<0> the nvidia for sure
<1> heh
<1> are you an EE?
<7> no he is just a idiot
<1> heh
<0> http://hyper.sunjapan.com.cn/~hz/PIC/picnic/screenshots.html
<0> actually that one has the ne2000 chip integrated into the board but I seen ones that used a normal old pc isa n2000
<1> im studying EE right now.. i want to do something with hardware one day
<0> no i just study ee for fun
<0> I started ee in college but didn'twork out
<0> left that college after 2 of 4 yrs
<1> howcome? it's very interesting
<8> umoms didnt work out
<0> went to a communityt college got ***ociate in cis/telecom in 3 yrs
<0> worked for the college for 5 yrs
