Hi, I recently damaged a Bios chip 25R256JVEN, I cannot find the same model number and letters, Is there any difference between the chips that ebay sells and this one? Thank you for your knowledge.

Hi everyone. I used Acer Travelmate 6292 with BIOS v.13112, Santa Rosa 1436 (VGA Bios version). This BIOS supported title letters for creating password on HDD.
A week ago an element on textolite burnt and I cant turn on laptop.
I thought that title letters support different types of BIOS.
I tried my new laptop lenovo and my friends old Acer and to regret nor mine nor his laptop doesnt support title letters in
Standart HDD 2,5 inches.
How can this problem be resolved?
Lots of BIOS versions of different types of laptops support title letters in password?...05-18-2024, 03:51 AM -
Hi.
I have some problem with old CRT TV Samsung model: CW-29Z338T, 29" size TV.
The problem is that letters and other text are not clear, text or letters are shadowed on the right side.
I found 2 capacitors on CRT Picture Tube Board.
47uF/400V was leaking very bad, the second cap 10uF/250V was bad ESR reading so i replace this cap also.
Replacement these 2 capacitors did not help nothing.
I try to reduce brightness, contrast and sharpness. There is very small effect on this shadow.
To reduce G2 down have more effect... -

Hi,
I've managed to take an image dump in BIN format of my Dell Latitude 5420, which had a Winbond 25R256JV chip installed.
I used an RT809F programmer to obtain the BIN, using the supplied iFix RT809F programmer application (latest version being 20220830).
The programmer automatically found the settings to read the chip but selected the Winbond W25Q256FV instead (my actual model isn't available on the listing within the software). The image came out fine - I did this multiple times to clarify the data being read was the same each time.
