486 DX2-66 Speed?

Post by Warwick Ward-C » Wed, 03 Aug 1994 05:51:14



What should a 486 DX2-66 with 8 Meg of Ram and a 16 Meg Swap file run at
if I compile a new kernel it takes about 20 Minutes or so to finish is
this acceptable?

Also if I do a dmesg it says the system is running at 33.22 bogomips is
this normal also what the hell is a bigomips.

Cheers,
Warwick

If you think it isn't, add more memory. This will increase the speed
of your system when compiling the kernel.

Ever heard of the Linux-FAQ? Now, it's time to read it.

I have a similar equipment and it takes about 20 minutes to compile the
kernel, too !
I think, that is the normal speed !

I have a 486 DX2-66 with 20 megs of ram so it only takes 10-15 minutes
to recompile my kernel, but I would guess that 20 minutes is perfectly
reasonable for your setup.  I also get a 33.22 bogomip rating.  I have
no idea what a bogomip is, however.

Okay guys, no need to reply anymore, apparantly accoding to about 10
other fellow linux'rs this an accurate speed to work under..

Thanks to all for the help.

1. 486 DX2-66 => DX4-100 in a laptop.

Hi,

I have a somewhat old laptop (Mitac 4022) with an Intel 486 DX2-66
processor. Since the 486 DX4-100s are really cheap now (BTW, there is
something 486-compatible faster than a DX4-100 out there?), I tought
it would be a nice idea to do an CPU upgrade in my notebook, if it is
at all feasible. From what I could understand in the manual, it seems
to be quite possible to do such upgrade.

I've already seen the chip and it seems to be a "normal" Intel DX2-66.

There are switchers to select the CPU from the following types: SX,
DX, DX2, P23S, P4S, and P24S. As you see, there is no DX3 or DX4, but
I think it's no problem since the settings for DX and DX2 are
identical.

There are also switchers for the CPU-frequency, but just two choices
are available here: 25 and 33 MHz. This is ok, because the DX4-100
operates at 33 MHz, right?

There is also a jumper for selecting between a "S-series CPU" and a
"normal CPU".

The manual has nothing about the CPU voltage, but I hope it's already
cared of in the CPU-type settings.

What are my chances of succeeding in such upgrade, in your opinion?

Thank you in advance for your answer.
