How to create a new bootable image for CF card for BOOK 8088

[Romfos]

Hi,

I know that you are not book 8088 support, but you are very experienced guys that probably could help

goal: Make bootable CF card (1GB) with fresh msdos 6.22

When I'm try to create empty image with MSDOS 6.22 - book 8088 is not able to boot on it. My modern notebook book is able to boot from this image I know that old system uses CHS system and probably this is source of the problem, but how can I configure it for my new CF card? I don't see any setup menu i bios for CHS config

Ranish Partition Manager show me that CHS is 933,33,63, but how can I check - what values are in bios? (CHS of original card (500mb) RPM show me as 933,16,63)

1) When I create new image in dosbox: IMGMAKE 8086_cga.img -t hd -nofs -force -chs 993,16,63 2) mount it IMGMOUNT 2 8086_cga.img -size 512,63,16,993 -t hdd -fs none 3) Boot from msdos 6.22 install disk BOOT disk1.img disk2.img disk3.img 4) Install msdos, next-next-next 5) burn image to CF card 6) copy additional software via default windows explorer ... boot failure

Thank you

I think I was using Free DOS FDISK.

FWIW, I put my Book8088 CF card in an IDE adapter and I got 63/255/63 CHS values.
