CUSL2-C problems (BIOS?)

Hello,

I have just bought a used computer which I believe has a CUSL2-C motherboard. I saw that richboud recently receive some help with his board and was hoping that this is the right place to look for help.

I think I have a CUSL2-C since this is what it says at bootup and also it has no onboard audio or video (only parallel, usb and ps/2). It is currently running bios version 1008a.

I've had various problems/questions about this board and will list them in order of severity. But first, some specs (this is all obtained by guessing and looking at the hardware):

One 40mb hd (don't know the brand)
One 48x (I think) cd rom
A logitech serial mouse
A 3-buttons, no wheel ps/2 mouse
2 ps/2 keyboards that look the same
A floppy drive
1x128 mb pci133 ram
1x64 mb pci100 ram (I think)
1x64 mb pci100 ram of a different brand (I think)
ATI rage video card
19" Samsung 900NF

Software:
I've installed WinXP pro and Ubuntu 6.06 on it. Grub to dual boot. Also has one fat32 partition for exchanging files.

Problems/questions:
1. The floppy drive fails at boot up. (error code 40) I've tried to unplug/replug and reverse some connector cables at random but it still doesn't work. I doesn't work in any of the OSes.

2. Keyboard error or no keyboard present at bootup (but I *can* press F1 or DEL and it works). Keyboard also works fine in WinXP pro, grub and bios. The three lights flashes about 10 times at bootup (before primary/secondary IDE messages).

3. The keyboard no longer works in Linux (Ubuntu). I don't remember doing anything fancy before it stopped working. I remember changing xorg.conf from ps/2 mouse settings to serial. Then rebooted and everything (including the keyboard) still worked. Then I named (or formatted, don't remember) my FAT32 partition in Ubuntu and rebooted. Then the keyboard stopped working in Ubuntu (not even at console in recovery mode). However, I did manage to make the keyboard work once more by unplugging and replugging it at the login screen. It was behaving somewhat strangely (repeating keys as if they were stuck). But I logged in and managed to install an ssh server (so that I can potentially edit Linux files externally now). This was done with an external usb key/drive/pen. The unplugging/replugging didn't ever work again. Also, num lock, caps lock don't even work in Ubuntu. Also, booting with the live CD doesn't make the keyboard work either.

4. Whenever I turn the power off and then on again, the BIOS resets. If it was in jumper-free mode, it goes and asks me to put in a CPU speed (why can't I choose something below 1000mhz here?). If not in jumper free mode, it writes the errors listed above together with a checksum error (I've tried non-jumper-free with various dip switches settings but it always gave the same thing). This is mostly annoying because I have to reset the date every time.

5. I think the kbpwr jumper is enabled but I have a weird horizonal tower and can't reach it.

Thanks in advance,
zli

A couple of things spring to mind.
1. The floppy is a dud!
2. The mobo battery needs replacing!

Welcome to ABx zli, the original home of the ASUS CUSL2 board and all its variants. Some of us are still running CUSL2's and pop in from time to time.

Yippie!

Another CUSL2-C owner here at abXzone.

Wellcome zli.

From what i've been reading i would guess that the floppy drive is faulty. Try replacing it with another one.

The board's BIOS problems (having to choose CPU freq. on every power on) indicates that the BIOS battery may be faulty too. Try replacing it, or at least remove it, clean the battery and the contacts and put it in again. The battery may still be O.K. but the contacts could be corroded.

If i where you i'd use the ps/2 mouse instead of the serial one. Do both mice act the same?

Have you tried both ps/2 keyboards? Do they both act weird?

As soon as you have a working floppy drive, try flashing the BIOS with the latest version. You´ll find instructions on how to do it properly when aou search the forum here. (But i wouldn´t mind repeating them in this thread. abXzone members are friendly members)

Using different RAM's (pc100 and pc 133) can also be problamatic with this board. Using RAM modules of the same size and speed is highly recommended.Maximum amount of Ram for this board is 512 MB.

What kind of CPU are you using? 1.13 GHz is the fastest "regular" CPU for this board. But you can put a modded 1.4 GHz Tualatin in it. (As you can see in my sig mine runs at 1.6GHz).

Fell free to ask any questions you may have about the board here.

Greetings

Dru

Ok, thanks guys.

I don't currently have another floppy to test. Can this board boot into DOS from a USB key (or maybe with the help of grub)? I've downloaded lots of stuff off of the ASUS site. It seems that its possible to flash the bios from Windows. From your experience, how safe/unsafe would that be? (I don't expect to be able to get my hands on a floppy anytime soon) Also, should I try using the beta bios or version 1009?

Actually, the ps/2 mouse doesn't work in either OSes. When I had tested the system with a different ps/2 mouse (mitsumi laser with wheel), it worked in both OSes. But that was a mouse I borrowed from my office. If you want, I can tell you more about the trip this computer has made before getting to my home. When I tried to force the ps/2 mouse in the BIOS (I forgot the option name), the keyboard stopped working completely. Since my bios is always resetting, I just shut the power and reset it. Also, the ps/2 mouse I currently have does work (I tried it on a different computer).

Both keyboards have the same effect. However, both keyboards look exactly the same and I haven't tried a different brand/model. wish I knew what the actually speed of my CPU is but you would have to teach me how to tell by just staring at it (or using some software). I think that the ones that sold it to me didn't know. They probably claimed it was a 1000mhz just because that's what the boot screen showed (and thats what the dip switches were set to initially).

I had to reduce the RAM speed from 133mhz to 100mhz to make it recognize all 256mb of ram. I'm thinking that 128mb is too little for WinXP and/or gnome. Could keeping different kinds of ram in there do some damage in the long run? If not, I might just end up with a WinXP only system.

Also, from the state where I bought the system, the only thing that I've added are a network card (forgot to mention this in the last post) and the 2x64mb ram.

Finally, where is the battery and how do I remove it? And maybe, more importantly, how do I put it back after I remove it? I'm not particularly experienced with hardware.

A final remark: Everything (except floppy and funny keyboard error) used to work with the settings I had (which includes 256mb ram, dual boot OS, 1000mhz, serial mouse, etc) until I rebooted at some point. This is really the strangest thing.

Btw, I've also read some of the "BIOS destroyed on flashing, DON'T DO IT!" thread from the sticky graveyard which is also why I am reluctant to flash the bios.

I would hold off on the BIOS flashing for now zli. Try the battery first.
I seem to remember that flashing from floppy is safer than thru' Windows.

The battery is one of the thin round shiny things. Dru will be able to tell you where it is as he has the CUSL2-C. I have the plain CUSL2 and the battery is behind PCI slots 1 & 2. It's a CR2032 lithium cell. Also, near there is the clear cmos pinout - CLRTC.
You will need to short them out after replacing the battery.

Keep us in the loop as to how you get on!

PS the maximum amount of RAM is 512Mb for the CUSL2.

Hi zli!

Don´t ( never ever) try flashing the BIOS within windows. I destroyed mine that way, as have others here on this forum. Using a boot floppy should minimize the risks.

Can´t tell you the exact location of the battery right now (can take a look at my board this evening) but it´s position should be indicated in the manual. Removing it is simply done by slightly tilting and pushing it sideways out of it´s holder. How to put it back should be clear once you removed it.

No harm done in using the old BIOS until you get hold of a floppy drive. Flashing to the latest beta should by O.K. If you want to do some overclocking (raising FSB higher than 140 MHz) you should use the latest modded version (1009).

Using different kind's of RAM should do no harm. Using 256 MB RAM at 100 MHz is better than only 128 at 133 MHz.

Greetings

Dru

Hi Drufuss,

I thought 1 Ghz was the fastest P3 which could be installed on CUSL2-C.
Could you provide more detailed info about the "regular" 1.13 Ghz CPU for this board? P3, Celeron, Coppermine, Tualatin, 100 or 133 FSB?

Thanks in advance

My CUSL2-C system is still very smoothly running with BIOS 1014c.001.
This BIOS version can be downloaded from:
ftp://dlsvr03.asus.com/pub/ASUS/mb/s...815ep/cusl2-c/

If you're interested in it, there exists a tweaked BIOS version 1012b10twk as well which is provided at:
http://www.x86-secret.com/Download/i...1012b10twk.zip
However, I've no experience with this tweaked bios version, once developped by a French guy.

"A 1.13 GHz version was released in mid-2000 but famously recalled after a collaboration between HardOCP and Tom's Hardware discovered various instabilities with the operation of the new CPU speed grade. The Coppermine core was unable to reliably reach the 1.13 GHz speed without various tweaks to the processor's" quoted from wikipedia.

Now that you mention it, i think that i´m using this version http://www.x86-secret.com/Download/i...1012ctwkb2.zip now. (for CUSL2-C without audio, other versions are available for TUSL2 and CUSL2 with audio etc. etc.).
Read all about it here:http://www.x86-secret.com/articles/tweak/i815twken.htm

You have to use the modded BIOS to make AGPx4 possible with FSB higher than 140 MHz. (Bypass Asus "safety"-feature)

Hello everyone,

So I went to mess with the CMOS battery yesterday. I opened the case, looked for it and saw that it was obviously missing! There was clearly a plastic stand on which a shiny round battery should stand but no battery. Now that answers a few questions.



So I guess that my first question today is how compatible are these CMOS batteries between motherboards? I may be able to find some battery off of some even older boards. Alternatively, how costly are these. This system cost me 32$CAD for the monitor and 83$CAD for everything else. So I'd rather not spend much more on it especially since its still functional in windows now and other parts could potentially be broken.



I can only hope that the battery fell out during the 2 trips before it arrived at my home. But I can't see it anywhere inside the case. So my guess is that the battery was missing when the system was sold to me.



Btw, when I booted the system yesterday, I noticed that I had bios version 1007 and not 1008a as I thought.



Another note is that I will only manipulate hardware at most once per day (when I go home).

You can purchase a CR2032 lithium button cell battery, appropriate for your CUSL2-C, at almost any electronics-, PC components- and photocamera-shop. Or a shop where they are selling watches or hearing devices. May be right on the corner of your home.
Your spendings: approx US$ 0.50 a piece.
If online shopping is required, google for: CR2032 lithium button cell battery

Ok, so I bought a new battery (for 2.70$ CAN plus tax (everything is so expensive here)). I installed it (it clicked right in with a little push). I didn't find the reset (CLRTC) jumper location though. When I rebooted, the CMOS settings we finally getting saved (when I unplug the computer from the power source). However, I'm still getting the same keyboard problem (including the BIOS warning). I guess that from what you guys were suggesting, I should try and flash the BIOS now.

So basically the battery didn't fix anything except the resets on unplugging.

However, as you know I don't have a functional floppy right now. So I'd like to know if I can boot from my FAT32 partition or from my USB key or something else (maybe even CD, although, getting CD's burned around here might also be hard).
