Compaq Presario 1230 Laptop Accessing BIOS Setup
Hi,
I service TVs, etc. Once in a while, I service my own computers, one of which is a Compaq Presario 1230 laptop with Windows 98se I bought second hand a few years ago. You may consider this obsolete, but to me, it is very useful. Recently, during power up, I saw "Error, O2BO: Diskette drive A error". I removed the floppy drive, but I got the same error, which could be it's controller? I inserted a bootable CD rom hoping that the boot sequence might start at the CD rom, but it didn't. It must be A: drive first. Note: The HDD is fine because I removed it and checked it on anther PC. If I can change the boot sequence, I can do without the floppy drive, but to get into the settings by pressing F10, I have to enter a password. I don't have the phone number of the person I bought it from who lives out of town. I removed the RTC/CMOS battery (soldered in) and waited 24 hours hoping that it may "clear" the password requirement, but it did not. Maybe I should wait longer? Pressing F10 presents a screen that says, "Phoenix BIOS Setup Utility" followed by a prompt for a password. I tried some by guessing, but it didn't work. I hope the password isn't stored in the BIOS. Do you know a technique to bypass the password requirement so I can change the boot sequence? Thank You in Advance, John PS, Remove "ine" from my email address |

Compaq Presario 1230 Laptop Accessing BIOS Setup
a few years ago. You may consider this obsolete, but to me, it is very
useful. I don't... Hi, i'm from Italy, once in a while i put my nose in the US repair ng, but it seems incredibly DEAD!! Why??? It's the wrong one? There are many? It's my provider? bah.. Do you know a technique to bypass the password requirement so I can change the boot sequence? U have 2 ways to fix the problem, crack the passw or fix the floppy problem, but since u maybe will have to access the bios in the future it's not bad starting to crack it.. i know the pass is stored in many laptops in a chip that if i remeber what i have read is common to many producers, so if u want, start to find the chip name or dismount the laptop to see, if u find that the chip is the same as the Ibm thinkpad T2x (T20 etc..) series u can find in internet a little project to crack it, with a very little homemade hardware and a little software to read it's eprom and decode it to pull the passw. Bye |
