ISO loaded as CD into memory is not seen by FreeDOS #102

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Extract HBCD v5.1.1 to FAT32 USB FLash drive
2. Install latest chenall 0.4.5c grub4dos to MBR
3. Boot in QEMU and choose UBCD FreeDOS R1.44 (Based on NwDsk V3.40)  menu
4. At blue/white pop-up, select Launch

CD (drive T:) is not found.

But this works OK if syslinux is installed instead of grub4dos.

Also can be fixed by using memdisk to load the ISO.

DOES NOT WORK!
title UBCD FreeDOS R1.44 (Based on NwDsk V3.40)\n FreeDOS boot disk used to run 
many of the other DOS apps on the UBCD. Revised\n version of Eric Veermans' 
FreeDOS NwDsk 3.40. Addresses many bug fixes,\n performance enhancements and 
compatibility issues.
map --mem /ubcd/images/fdubcd.iso.gz (hd32)
map --hook
root (hd32)
chainloader (hd32)

but
kernel /boot/syslinux/memdisk iso
initrd (bd)/ubcd/images/fdubcd.iso.gz 
does work!

What is the expected output? What do you see instead?
CD should be detected by DOS

What version of the product are you using? On what operating system?
UBCD 5.1.1 ISO extracted to USB pendrive

Please provide any additional information below.

Thanks for the report. It is almost the same issue as issue 99: eltorito.sys 
unable to mount emulated CDROM drive.

There should be no solution unless the eltorito.sys be fixed (or say, enhanced, 
if someone would like the latter word).

It should be not a problem of grub4dos.

I will close this report later.

Actually, the UBCD FreeDOS entry works fine on a REAL system, it just does not 
work under QEMU (and maybe other emulators?).
