I have a very strange issue with the BIOS SPI chip of an ASRock B650M PRO RS motherboard.
The SPI chip is an Winbond 25Q256JWEQ model (1V8).

The Flashback function of the motherbaord is also not working, despite all instructions followed correctly - I'm 100% sure of this.

I am being employed at a company where macOS installations are common, and I was wondering if you guys had any tips or tricks to deploying hundreds of macs from recovery mode (we use macdeploystick)! If any of you guys have any cool keyboard shortcuts or commands to making macOS installations a bit faster or anything lol I would be glad to know!😀-

by tk3000My venerable and old laptop (Toshiba Satellite P75-A7200 equipped with an i7-4700MQ, circa 2014) and previously a powerful machine during its heyday is no more. Have been using it for many years, but about 3 months ago it went kaputt for no apparent reason (left it on overnight [normally it goes to standby mode after some idle time], and in the morning it was cold dead with no boot, no post, no leds; nothing at all).
Since the 1990s I have been building custom desktop computers, etc; but it has been few years since my last built one and for the last 15 years I have built very few... - Loading...
