Compaq Presario R3000, HP Pavilion zv5000, HP Compaq nx9105: 90nm CPU Support

Thank you

When I flash it with dos version of phlash16.exe (via usb floppy drive) I get error , it says Bios may be Corrupt (checksum not zero). Is it normal? Must I bypass that error?

[DeathBringer]

Is it normal?

No. I'll try to fix.

[IrRaziel]

In the meanwhile I flashed it, now I get blank screen. Bios is bricked

Tomorrow I will try with a rescue disk

[DeathBringer]

You need to download original BIOS - http://ftp.hp.com/pub/softpaq/sp30001-30500/sp30397.exe
Open it in WinRAR to extract 08A0F35.exe and unpack it by WinRAR too.
Replace 08A0F35.wph by modded one and start FLASH.BAT in Windows XP

[IrRaziel]

The computer now is bricked. Doesn't start. Fan, led, but blank screen

I created a phoenix crisis disk (floppy) and tried various key combination (FN + Esc, Win + B , FN + B) but floppy read for 2 seconds and stop

in the crisis disk I put 08A0F35.wph renamed bios.wph (it's in my first post here)

I press the combination and then press Power button
But nothing

[DeathBringer]

So you need a hardware programmer to recover.

[IrRaziel]

Yes unfortunately... I think I must buy a CH341A with correct optional (compatibile with this chip) and learn to use it :-(
Often this old systems are different from modern comptuer

I also tried with a usb key... nothing

The floppy drive (with the crisis disk in it) reads two times for a couple of seconds, then stops. I don't know If I make some mistake, I will try again later

Or perhaps this computer has a different combination because it's old, I will search on line. HP zv5000 series and HP nx9105 seems to have same motherboard, I will search about them also, if there is a bios recovery procedure

[IrRaziel]

A question: if I will get an other motherboard Compal 08A0 (from a R3000, zv5000 or nx9105) I can change phisically the bios chip?

Put in my dead R3000 the bios chip from a zv5000 for example? Can it work?

[DeathBringer]

Yes, it will work.

[IrRaziel]

Hello. I bought a wasted HP zv5000 and moved its bios chip to my Compaq Presario R3000. Now it works again

However now I'm afraid to flash an other modded bios to get a cpu upgrade. I don't want risk to brick it again

This bios is old-style and it is also incompatibile with the spi programmer CH341A usb
