Hi!
Here some logs I took, wile booting... keep in mind that computer is AHCI only (does not support IDE). So this is why it is so hard to detect the CD rom driver. Logs: JemmEx v5.84 [02/12/24] JemmEx loaded Message Logger v1.00 (c) 2023, Jerome Shidel, BSD 3-Clause License 256KB of XMS memory allocated for color logging.

This is LGDT [cs:0x678] at e800:06da, so apparently you have some sort of controller related BIOS extension there which directly uses protected mode, incompatible with EMM386. This could be a disk, USB, network or similar controller BIOS and you could try to boot without EMM386 (JEMMEX) but maybe you could also convince the controller BIOS to cooperate via VDS. Good that start-up continued nevertheless, just without CD/DVD.
