commit 9dc0033e4658d6f9d9952c3c0c6be3ec25bc2985 upstream.
Enhanced Strobe (ES) does not work correctly on the ASUS 1100 series of devices. Jasper Lake eMMCs (pci_id 8086:4dc4) are supposed to support ES. There are also two system families under the series, thus this is being scoped to the ASUS BIOS.
The failing ES prevents the installer from writing to disk. Falling back to HS400 without ES fixes the issue.
