The Gateway md2614u laptop has a Radeon HD3200 iGPU.
It would seem that there was only one mobile chipset with the Radeon HD3200, and that was the M780G.
The Gateway md2614u laptop uses SATA for it’s internal disk drive (no idea about its optical drive, but that doesn’t make a difference)
The M780G chipset supports AHCI.
Yet, like many laptops, the Gateway md2614u has a very locked-down BIOS and does not include an AHCI setting and instead just always locks the internal SATA disk to “IDE” mode.
In our current day and age of SSDs, having your SATA port(s) locked to “IDE” mode means no TRIM for you!
(and just to be clear, this laptop predates m.2 SSDs by something like 5 or more years).
Soime BIOSes from that era support a secret “advanced” BIOS menu. Likely enough your BIOS is made by Award. If so, hit Ctrl-F1 and see if that gives you more options.
I just learned about this—Phil’s Computer Lab is a Youtube channel that covers a lot of vintage and retro computing hardware, and he was bitten by a bug that plagued me for days—early Radeon AGP cards would crash on AMD boards with VIA chipsets that supposedly had robust and reliable AGP support. Apparently not, I thought at the time, and it nearly defeated Phil as well in the modern age, but someone in his audience knew the fix: Press Ctrl-F1 to enable advanced settings and set VGA shared memory (with the unused VIA iGPU) to 0.
