The second linux example builds to /dev this is designated tempfs space and data will be lost on reboot. I commonly put images there and use ddrescue to transfer from ram to hdd and back. /dev/ram0

For using Ram as hdd for windows on linux:
sudo modprobe brd rd_nr=1 rd_size=2457600 ; 2.5GB image
sudo rmmod brd ; to remove

use -hda /dev,ram0 for pc hda or
-drive file=/dev/ram0,if=none,id=disk for other devices.

ddrescue -dvf /dev/ram0 /home/ram2.img (backup)
ddrescue -vf /dev/ram.img /home/ram.img (restore)

format with dos/windows in qemu with fdisk and format

For using q35 and windows 98se:
Use setup /p i after adding drivers from Intel INF Driver V8.3.0.1013 and all main board device drivers will be installed during setup. Make sure to select win98gold folder from Ac97 drivers or it wont work. (scsi driver needs to installed after install)

vhost-user-gpu -s /run/user/1000/vg.sock & qemu-system-x86_64 -M q35 -L . -m 512 -display sdl -net none -cpu host -smp 1,sockets=1,cores=1,threads=1 --accel kvm -chardev socket,id=vgpu,path=/run/user/1000/vg.sock -device vhost-user-gpu-pci,max_outputs=0,chardev=vgpu -boot menu=on -serial none -parallel none -audiodev pa,id=ad0 -device AC97,addr=05,audiodev=ad0 -device lsi,multifunction=on,id=scsi0 -device scsi-hd,bus=scsi0.0,drive=disk0 -drive if=none,id=disk0,media=disk,file=/dev/ram0,format=raw,cache=none -device scsi-cd,bus=scsi0.0,drive=disk2 -drive if=none,id=disk2,media=cdrom,file='cd.iso' -device scsi-cd,bus=scsi0.0,drive=disk3 -drive if=none,id=disk3,media=cdrom,file='cd.iso'

I have been able to install on q35 with kvm on during install, after initial boot, disable virtual memory before installing lsi drivers "dc-390". Or setup RAM drive for virtual memory if needed.
