@wyatt Also glancing from the #PC98 architecture and specific quirks that #Linux accounts for in menuconfig it's most likely not gonna be enough to "just boot the #i486 version of @OS1337"...
github.com/OS-1337/OS1337/blob

  • Tho given the fact this is just a #toybox + #musl / Linux Distro that is barely booting using #syslinux and able to spit out a 80x25 MDA console, it is in an early infancy.

As for the specifics of the #PC9821+ and their detailed hardware I'm clueless beyond the Wikipedia Article and can only Assume anything before a (RAM-upgraded) #9821Ap & #9801BA is off the table and a #9821Af or better is desireable as the 14,6MB RAM limit will really become a problem quickly, as I'm pretty shure it's impossible to get linux-6.6.6 run on anything below 8MB at all and most recommendations hint that 16MB is more often than not a practical limit (tho that may be becaise 10/12/14 and other "asymetric" configurations were already avoided back then)...

  • The #9821Ce should be workable in theory tho again that's just me reading a specsheet.

On the flipside I did manage to install #WindowsXP on machines with 32MB RAM and actually get them to display a desktop (abeit with seconds per frame instead of frames per second) so this is more likely a question of chipping down things.

  • Worst-Case one could see to build a bootable CD-ROM or dd something on a #BlueSCSI or similar...
Made a new video: Setting up an NEC PC-9821 Ce2 with a fresh hard disk and DOS 5.0A-H (using a very large IDE hard drive). Also CD-ROM drive setup.

As usual correct me if I'm utterly wrong about something.

URGENTLY REOPENING #MUSIC #COMMISSIONS AGAIN – Delivery expected for no earlier than March 2025

On August 17, my computer (the device I use for all my music productions) became out of service by an exploding
power supply, shortly after recovering from a tropical storm-caused blackout. It cost nearly US$150 to replace that PSU with a new unit, which still refused to power on the computer because it too got damaged, somehow (turned out, the peripheral power cables connecting the PSU to the hard disk & optical disc drives were either shorted or incompatible with the new PSU, thus damaging it). A month later (September), the new PSU was again replaced but also this time the peripheral power cables were also replaced, & only then my workhorse PC came back alive… only for the new PSU to again explode now on October 16 (two months after the first PSU’s explosion & one month after being replaced together with new cables). So, once again, my music-production PC is AGAIN out of service, & who knows if now there is a new component that needs to be replaced before it again explodes my next PSU?

So, I need to AGAIN reopen music commissions & need to fill in as many
#commission slots as possible to raise enough funds for the replacement parts (because now it’s not just the PSU nor its peripheral cables, it could now also be something else & I don’t know what it is).

If there is a
#game-music track or #anisong you want to see turned into a #PC-9801 version (instrumental #chiptune only) &/or a #PC-9821 version (with synthesized vocals from #VOCALOID &/or #SynthesizerV), please kindly hit me up on the #Ko-fi link below & contribute as much as you are financially able to contribute. Also be patient about the delivery of the finished commissions, as I cannot start working on any of them until all the damaged parts are replaced & the PC is again able to turn on & boot up. You can also review my two #Carrd links (below the Ko-fi link) to see which synth voicebanks I own.

URGENTLY REOPENING #MUSIC #COMMISSIONS – Delivery expected for November/December 2024

My computer (the device I use for all my music productions) got damaged by an exploding power supply, & I have no estimate of how much needs to be replaced & for how much money (beyond a blown PSU, which cost nearly US$150 to replace yesterday, & still the new PSU cannot power on the computer). So, I need to reopen music commissions & need to fill in as many commission slots as possible to raise enough funds for the replacement parts.
If there is a
#game-music (#gamemusic) track or #anime song (#anisong) you want to see turned into a #PC-9801 (#PC9801, #PC-98, #PC98) version (instrumental only) &/or a #PC-9821 (#PC9821) version (with synthesized vocals), please kindly hit me up on the #Ko-fi link below & contribute as much as you are financially able to contribute. Also be patient about the delivery of the finished commissions, as I cannot start working on any of them until all the damaged parts are replaced & the PC is again able to turn on & boot up. You can also review my two Carrd links (below the Ko-fi link) to see which synth voicebanks I own for #SynthesizerV & #VOCALOID as well as examples of my #chiptune portfolio (including three past #commission pieces).
