Asus 1005A BioS

I have heard that its buggy, but a final release has been released to support jumper-free multiplier setting.
 
Its not really that buggy, the biggest bug I found was you need to have Virus Detection on in the BIOS to boot off ATA100 but thats about it.
 
Dulanic, if it's what you say. I'm sure that for those who installs Windows through their ATA100 drive would have some problem if they don't boot up from the ATA66 port. Since windows don't like the virus protection thingy set to enable in the bios.
 
Windows has no problem with the virus protection in the BIOS from my knowledge.... I installed both Win98 and Win2000 and both work fine. And Ive installed both on both the ATA66 and ATA100 before.

As for the temp problem I did a work around.... I used WPCRSET to modify the registers and changed register 52 from 6B to EB and that fixes it. Its obvious Asus wants it like it is or they would have changed it back.... because its just one single option in the KT133 registers to fix it. But it works fine for me so Im happy.
 
It did not support HLT when I tried it even though Dulanic says he found a work around for temp problem - not sure if this refers to HLT - this is key since it is the only known way to cool down this cpu when idle (unlike the P3 or K6-2 before).
Will try Wpcredit and Wpcrset to see what happens. DO not know why Asus refuses to support HLT in these new Bios updates.
 
There must be some reason..... They could fix it with on register change so they have to be doing it on purpose.
 
Anyway just flashed and tried the EB fix at register 52 and it works. Temp dropped by 10C at idle. It must have something to do with those 2 items that are greyed out in BIOS for PCI/DRAM. Still have the virus check enabled in BIOS for booting purposes. A bit faster though. Heck the sound is f... up - man oh man - back to 1003 hacked. This is a test of the human endurance. First time I have ever experienced so much trouble with a board.
 
Regalk this is what I know.... that register has nothing to do with the 2 greyed out options because they are only greyed out for Durons not T-Birds and I have a T-Bird.... the sound seems to screwup for Durons only from what I can tell.... with T-Birds this fix works fine.
 
i also tried this register hack and it messed up my soundcard, got horrible crackling sounds for everything. my temps did drop from 107 to 96 but it isn't worth it without the soundcard working right. to date i have not seen work around for this problem. BTW this was with the 1004D bios
 
What i have to go get a T/bird now - O sh...! I am going to sit tight with the 1003 modded and wait on the 133A boards to come out from MSI. You are right about the T/Bird-duron Bios settings I forgot about that. Patience boy.
 
1005a is the first BIOS i've actually kept using since 1003 (unhacked).
So far so good.
How do I find out what revision my board is?
 
Dulanic:

What temperature problems? I'm having constant heating problems with my A7V. I've tried two power supplies, three processors, four coolers, and even an HD cooler. My temp reading are close to 60°C with the case closed. Very weird.
 
kuk with 1004 and 1005 the CPU is always under full load so your idle temps are like 1C below your full load temp.
 
Phuz: Look between the PCI slots. It is stamped on the board between two of them.

Kuk: If you are using a Duron on a 1.02 board then I recommend using bios 1003, disabling software cooling, and enable PCI master read cache. Your temps will drop. I dropped near 10c.

There is some good info and a good bios 1003 mod that I am using Here if you are interested.
 
nope ... always on full load is not an issue here. 🙁

Still searching for answers ....
 
Yes it is an issue.... it isnt technically under "full load" the MB just doesnt let HLT command through to the CPU which is what causes it to become cooler when its idling.
 
Only problem with the register 52 hack is that it also SLOWS HD access way down. Slowed my Read Burst Speed down 70%. Tested it with HD Tach...
 
awinner thats what Ive been hearing.... And yesterday when I ran HD Tach I noticed my burst rate was sometimes slow, but when I tested it today its been fine so Im not sure whats up with that..... Also it doesnt seem to effect any load times so Im not really sure about that.
 
I guess those items greyed out in BIOS for durons has a relationship to sound & Register 52 since for T/Birds they are not greyed out and sound works. HD access looks affected. So what do we have so far
1. HLT does not work
2. Reg 52 fixes HLT for T/Birds only but messes with HD access
3. Durons are screwed
4. Did not like 107FSB on my box screwed up Win explorer - had to reinstall Windows.
5. Anything else


6. Wait for 1005 B C D or ???
 
Update:
I have checked that the item PCI Master Read Caching that applies to the T/Birds only affects the HLT command. AFter flashing to the 1003 newly modified BIOS (Promise now ver33) it stayed at 49C. WHen I enabled PCI MRC in Bios it dropped to 40C.
Therefore what 1005A does and 1004C (haven't checked 1004D) is to disble this for durons and causes the temps to stay at full load. WpCrset screws up sound and HD accessing when you change register 52 to EB for durons only. Stay tuned
