No dice. I tried using install64.fs, but still it tells me of some mythical 1024MB drive "sd0", of which fdisk "can't read sector 0". Using 6.4 did get me a few more lines about sdhc: sdhc0 at acpi0 SDHD addr 0x90a02000/0x1000 irq 44 sdhc0: SDHC 3.0, 200 MHz base clock sdmmc0 at sdhc0: 8-bit, sd high-speed, mmc high-speed, dma sdhc1 at acpi0 SDHC addr 0x90a00000/0x1000 irq 47, gpio sdhc1: SDHC 3.0, 100 MHz base clock sdmmc1 at sdhc1: 4-bit, sd high-speed, mmc high-speed, dma The lines about sdhc1 and sdmmc1 are new, not there in 6.3's dmesg. This seems very strange to me. How is the system just inventing a drive exactly 1.0GB? I have no such drive, I swear. What does it indicate that fdisk can't read sector 0? I never got the understanding from the install faq that I would need to pre-format my drive in any way. Is that correct? Thanks for any advice!
